This is not about libastral, it's about pure functions (those without

Regarding "runtime library opening" (I suppose, you meant dlopen and friends),
then I suppose, you've found an exception to the rule, but maybe you are wrong.
I'm not a developer of Nix, so I can't say more.

It can always be reverted if you don't "destructively update" (overwrite) files
and if you can guarantee that filenames do not clash.

I'm not interested in your opinion if it isn't backed by facts, I'm interested
in *informative discussion*. I don't say that dpkg/apt are bad, on the contrary,
I think they are good, but we aren't talking about personal tastes.
