Re: [jakarta.ee-community] Fork Eclipse MicroProfile Configuration as Jakarta Configuration.
I now see that Steve started a new thread "Options for Jakarta EE and MP alignment" to discuss exactly what I suggested.

Please go read that thread and join the discussion there. The question is not about the quality of MP Config or forking/not forking. We sgould stop arguing about it. It's about which options we have and which is the best one.

I think we should pause for a while and thnk why this thread started. The profound reason is that it's not clear whether JakartaEE can adopt MP specs such as Config. It seems that people not affiliated with MP mostly think that it can't because MP with its pull model can't provide enough stability guarantees for JEE. People behind MP mostly think that it can or will be able to do so in the near future, at least for some specs.

We should resolve this question first before going into disputes whether to fork MP config or not. 

So, is it possible that some JakartaEE specs (Otavio named JPA, JNoSQL and JMS) will be able to consume MP Config after by the time JEE is released? That should be in about 18 months I guess. Or is it not possible and forking MP specs is the only option? 

Last time we talked about it I remember the answer was clear No because of IP reasons. Would it be possible when MP has a WG? Or something else is required? Maybe some guarantees from MP on top of the pull model?

 Regarding stability it looks like not every container based on Jakarta EE also works that well with MP Config:

Of course Mike knows better than anyone else,  that Eclipse Foundation often saw more than one project accepted with exactly the same goal:
https://www.eclipse.org/m2e/  is still around although it can also be seen as "mature" and "stable". There was another one roughly around the same time, IAM, see https://www.eclipse.org/projects/archives.php (there was even an Eclipse project called "Corona" once ;-) which did not make it that long.

So there would be nothing wrong if enough people (either from the old JSR or different projects dealind with configuration) gathered around a Jakarta spec that could be a "fork" of mp-config or something "inspired" by it and others. Of course using a working piece of code can't hurt, but claiming "MP is the only place where innovation happens" while no significant commit is seen on Github over the past 6 months denies reality compared to several others like Helidon: https://github.com/oracle/helidon/graphs/contributors 
I won't even mention Spring and Spring Boot because their adoption and ecosystem around them is undeniable.

Speaking of Dropwizard, while it was already stable and mature before the idea of MicroProfile even came up, a kind of subset from Dropwizard Config https://github.com/joschi/JadConfig is also a notable example for an annotation based approach.

You are simply factually wrong in this regard.  You're defining
"caring about compatibility" as being synonymous with "forcing strict
compatibility rules", when this is not true in any respect.

I voted "Pull" because the chief goal of MP ought to be to meet user
needs effectively and quickly, even if that means (in the worst case)
bumpy compatibility at first.  As I said, compatibility is a quality
measure (just one of many) and it arises from a good specification.
Making a specification be compatible doesn't make it good or useful.
It's far better to add compatibility restrictions *after* the
specification is already stable, rather than to add such restrictions
to a specification that is still rapidly developing (thereby greatly
diminishing its usefulness in the name of stamping a logo on it in the
short term).  This is (IMO) a good indicator of when it makes sense to
"graduate" a spec into Jakarta.  The consumers of Jakarta are looking
for long term stability, and that comes from quality, not from a
compatibility contract.

Voting "Push" would have done nothing to improve the quality of
specifications and would have obstructed the process of cross-vendor
standardization - an already inherently politically and socially
obstructive process.  It was a very cynical option IMO.

That is even a stronger argument against using a feature like MP Config as is instead of a "fork" or writing something heavily inspired by it from scratch in Jakarta EE.
