So you will make each build always do two byte-compilation passes
where today we have just one?  And the first one of these will use
only *.el files, including for those that are preloaded into
bootstrap-emacs?  Doesn't that sound like a significant slow-down of
the build?

Also, what about native-compilation, with or without AOT?
