Because there's a lot of functions out there, which work for the local
host, and should work also for remote hosts. See for example
vc-git-grep, which has

--8<---------------cut here---------------start------------->8---
(let ((default-directory dir)
      (compilation-environment (cons "PAGER=" compilation-environment)))
--8<---------------cut here---------------end--------------->8---

compilation-environment will be propagated to process-environment later
on. And the setting for PAGER is needed for both local and remote
instances of vc-git-grep. There's no special code in vc-git-grep for the
remote case.

Hmm, I don't see it immediately. Maybe we could discuss this in a
separate thread, where you specify in more detail what you like?
Perhaps, connection-local variables are the solution for you.
