I worry about it slightly mostly because I'd rather not modify
loadup.el, especially given that the motivation is an error message that
isn't really causing any harm.

I checked whether my original modification made any difference, and the
answer is a few seconds. bootstrap-emacs is replaced by emacs after the
bootstrap build anyway (not sure why since actually, since I don't think
bootstrap-emacs is used again).

The former is true, but this *should* speed up the build (albeit only a
little). I don't think we are doing the latter, except for
'w32-convert-standard-filename and only on windows.

Yes, I did, but wasn't sure what extra dependencies the Emacs makefile
was allowed to have. I guess it already uses find and awk.

Also, I thought about building a bootstrap-emacs to generate loaddefs.el
(and nothing else), then another bootstrap-emacs to do what the current
one does. Or, split the loads and the bit which does the dump in
loadup.el and see if I could get temacs to do what bootstrap-emacs
currently does.

I was trying to be as conservative as possible, especially as the
dumping proceedure may change significantly soon. I guess my changes to
loadup.el do not qualify as that conservative now.
