Hi Ludo,

> Clearly there’s a tension between that and keeping Guix open to changes.

That's indeed the main problem and here as elsewhere, it is often a
topic of heated arguments.

My point of view (long form:
https://hal.archives-ouvertes.fr/hal-02117588)
is that software projects should adopt a backwards compatibility policy
early on, state it clearly in their documentation, and stick to it. That
prevents misunderstandings, bad surprises, and heated debates.

As for what that policy should be for Guix, that's a more difficult
story. For projects with versioned releases, I like the principles
of semantic versioning, but Guix is more of a rolling-release
project. (Test question: does anyone know what the current Guix version
number is? Does anyone care?) I am not aware of any good precedents
in terms of policy for such projects.

I vote for discussing the second point before the first one. Names
should reflect the functionality behind them.

How about a unified command for constructing environments and profiles
declaratively? In other words, combine "guix environment" and the
declarative parts of "guix package". We could probably get rid of
the somewhat obscure "guix environment -r" in the process.

Cheers,
  Konrad.
