The effort here is all about extending the Extension Use Case, yes.

My thinking is that if we invent a new mechanism for extensions that are
not managed like contribs, we will find out that only contribs are going
to be using extensions.

Given the options of either growing extensions into being able to cope
with more than a single model or building an entirely new system having
most of the same feature set than Extensions, I'm pushing for the option
where we build on top of what we have already.

We can't use “package” because it means something very different in
direct competition. I have other propositions, but they are only
relevant if we choose not to improve Extensions… right?
