That's an example where the language is very tightly tied into the base. But
it's the case in general that all language environments we ship are tied to
the set of packages we ship at that time. Occasionally we do compatibility
packaging (python3 is actually an example of this), but in general it's
pretty painful. This is kind of creaky -- I'll use Puppet as an example: we
shipped it largely broken for several releases, because we updated Ruby to a
version not supported upstream. And we probably also shipped code that
required at least that new version. How do we decide in situations like
this? The traditional Fedora approach is to error in favor of going forward.
Because "first" is part of Fedora's fundamentals, I don't think we should
stop that, but we also could find a way to accommodate.

(And that's an example of something _within_ the distribution -- there's no
concern at all for user code.)

Yeah, so I think we're on the same page here.

Traditionally, yes, although there's been some heroic guideline-writing
recently.

I hope we are and can be more intentional than that. Conversations like this
one help!
