`version-satisfies` is *already* a generic function. We will add some more capabilities to the built-in version in ASDF 3.4, but library authors will continue to be able to implement their own extensions.

Mostly sounds good to me. Assuming you're still interested in more expressive version numbers and constraints for 3.4, I'll work on moving that off the back burner.
Adding fine-grained version constraints would be a big mistake.
I do not have the time to check this thoroughly right now, but I recall having suggested that ASDF shouldn't impose any constraints on version "numbers", but rather defer version comparison to libraries when they use a version numbering scheme that ASDF doesn't understand. This can be done by providing generic functions like version-> etc., and letting people provide methods on them.
There may even be an issue and a patch lurking around somewhere. Again, sorry for being fuzzy, this is just from the top of my head.
