Hi ZmnSCPxj,

Sorry for the delay in getting back to you.

I think it's OK to keep older versions if that's important, but it would
be good to specifically note why specific older versions are useful to
keep. I'm saying that because it's useful to know when an older version
can be removed. So, for 0.20 are there incompatibilities that you're
aware of?

The second thing is, I wouldn't immediately jump to the
(make-... pattern, and I would instead use package inheritance. See the
ruby packages for example [1].

1: https://git.savannah.gnu.org/cgit/guix.git/tree/gnu/packages/ruby.scm#n95

Package inheritance makes it simpler to make changes to individual
versions, and avoids the complexity of introducing a procedure.

Does that all make sense?

Thanks,

Chris
