AFAIR, I haven't seen a warning related to Emacs sources in there in a
long time.  I checked the *Warnings* buffer in my current session, and
none of what I have there is related to Emacs sources.

In pre-historic times I learned that it speeds up start-up.  These days
it's more trouble than it's worth as I routinely leave Emacs running for
weeks on end.  I've been meaning to disable it, but didn't yet bother.

However, I often see this practice recommended in the community, as some
people seem to care deeply about shaving that extra 0.2 seconds (or
whatever it comes up to) off their startup time.

We should note that this will lead to (potentially a lot of) warnings
from third-party packages, many of which are rather slow to react to
compiler warnings.  Maybe this will light a fire under them though.

Also, can we tell what is an init file and what is a package?

How do we see this affecting the first pretest?  I am ready to release
the tarball I have now, but if we want to change anything here I can
recreate and reconfirm with the relevant change at the drop of a hat.
