[Caveat: I haven't read the doc and am not familiar
 with native compilation.  Just commenting on what
 I see written here (which is without context).  If
 what I say helps, good; if not, please ignore.]

If that's not already pointed out explicitly in the
doc, it would help to do so.  It can help _greatly_
to understand not only what happens but some of the
logic behind that design.  Once someone reads what
you wrote there, things are much clearer, I think.

Again, please point that out explicitly (though this
one will be familiar to longtime Emacs users, as the
same logic has long existed for *.el and *.elc).
