From personal experience, no.  Even if you compile code ahead of time,
there seem to be some leftovers that are deferred.  guix-emacs.el is an
oversight, but apart from that I also other leftovers (possibly from
init.el?)

In Guix, this is more or less a user choice – we advertised the
transformation by which you can opt-in to AOT compilation in a news
entry.  Also, enforcing ahead-of-time compilation does not fix the more
pressing issue of packages breaking with native compilation ;)

To quote Eli:

I think this reasoning really falls flat in presence of any non-Emacs
package manager.  Like, obviously wanting to natively compile packages
managed by (dpkg, rpm, pacman, emerge, guix), but not natively
compiling a random elisp script you just downloaded from the web is a
legitimate use case.
