I beg your pardon?

There is no need to be defensive. Instead of being in denial about a
missing use-case, it's much more productive to find ways to improve the
software. For example, it could be possible for a Nix expression to
declare certain parameters as "pure", meaning that they don't need to be
incorporated into the hash. An expression "foo" that supports make's -j
flag, for example, might want to receive an argument "cpu_count". Still,
instance of (foo 4) and (foo 8) are the same thing. It's not like
something like that couldn't be supported in Nix. The only thing that
might stand in the way are egos, because you can't fix problems that you
can't admit to exist.

I did, and I was asking him this very question again because I received
no response. Please don't get me wrong, I don't mean to appear
impatient.
