The following is my personal view. While I am approaching this from an
Apache Tomcat perspective, I'm not speaking on behalf of the Tomcat
community.

Pruning - No view as it doesn't impact the specs Tomcat implements.

Package Renaming - I lean heavily towards the big-bang but see below.

Backwards Compatibility - I'd like so see the results of some
experiments to see how some of the proposed solutions might work before
firming up on the exact requirements.

API Compatibility - I'd like to see the API elements that have been
deprecated for many years finally removed. I wonder if it is worth
having a more defined process for removal such as "deprecated in n
releases and removed in the n+1th release"

Enhancements - Agreed

Profiles and Optional APIs - No view

Java SE and modules - Agreed

Microservices vs. Containers - No view

Microprofile - I think this is primarily a decision for the Microprofile
community

TCK - I'd like to see responsibility for the individual TCKs devolved to
the individual spec projects. This should be possible without having to
split the current TCK project into its individual specs.

Timing / Release frequency - I think that major releases (new features,
API changes etc) every ~2 years with maintenance releases (no API
changes, bug fixes, clarifications) every ~6 months strikes a reasonable
balance between the desire for new features, the desire for stability
and allowing time for the community to test / experiment with / evolve
new APIs before fixing them in a specification. I suspect it will take a
couple of releases before we are in a position where the above release
pattern works.

In terms of the timing for Jakarta EE 9, I'd like it to be ASAP but I
suspect the backwards compatibility work to handle the package rename
will be sufficiently complex that ~12 months would be a reasonable estimate.

Mark
