Re: [cross-project-issues-dev] Can we please stop using composite repos?

Thanks Ed and Mikael for responding.

I will change to use the staging repo to build & release my EPP product - I hadn't liked it in the past because it was a moving target as people updated the simrel contents.

However, I was only referring to multiple children providing just different versions of the same content - not composites with different content. There are specific failures when there are multiple children with the same content - yet none of the answers or the FAQ answer the question of the use case of having a single repo with multiple versions available. However, I don't understand this line from the FAQ: "and once we remove it, it will invalidate that target". How does changing the composite to point from M1 to M2 do that?

Anyway, this seems to be one of the things that are the way they are - I hope to understand but I am not sure I will.

Can the composite only include the current/latest version, or can someone educate me as to the value of having multiple versions?

It's a really good question.  It just seems to be a "habit" to compose multiple children, usually with some restriction on the number of children, e.g., the most recent n children.  But personally, just to make everything faster for the client and less overhead for the server, I would prefer to use a repo with a single child with the most recent version.  

So what prompted everyone to have this habit?  

AFAIK, it comes from the simrel process of "making visible" the repository to the world (after the quiet / mirroring time). See code comment in
