It is common enough for desktop PCs and laptops, which is the use case
I'm talking about here.  If you're hosting a server, chances also are,
that you have that much, if not more space available.  For cases, in
which you have significantly less memory available, there is a bare-
bones template.

I'm fairly certain you should be able to get test environments, that
fit this size via `guix environment', but if that's your plan, you
shouldn't do much else with the space you have.  Might I ask if you're
the kind to keep a separate /home?

"Please remove all my previous stuff whenever I upgrade a package" is a
rather specific feature request in my opinion.  I don't think there is
much room for bikeshedding different implementations of it, though of
course, Debian, Arch, Gentoo etc. are all different distributions, that
produce it as a side-effect of what they're actually trying to do.

How did other distributions "adopt this feature" in your opinion?
