That advice wasn't meant to be used for producing distributions, only
for your own use.

Because we don't have a good way of tracking dependencies between Lisp
files.

Why is it too bad for a distribution you do once in a while?  Let it
run in a separate directory, and you can meanwhile do something else.

How much time does it take you to bootstrap, btw?  And on what
machine?

No.  Which is why admin/make-tarball.txt, the file documenting the
procedure to produce a release tarball, says:

  2.  Bootstrap to make 100% sure all elc files are up-to-date, and to
      make sure that the later tagged version will bootstrap, should it be
      necessary to check it out.
