Yes, the "inefficiency" isn't much of a problem.  The main source of
inefficiency of bootstrap is the time it takes to byte-compile every
file.  The autoloads are negligible in comparison.

Also, reconstructing the loaddefs.el file from scratch is a good
practice, since it ensures we don't carry along old stuff from
ldefs-boot.el.  I.e. it's a cleaner bootstrap.

If it hurts, don't do that.
