Then I see no problem in the behavior you describe.  It's what is
expected.

No, Emacs with native-compilation always behaved like that.

The *.eln files produced as part of the build should under
native-lisp/ in the build tree.  The *.eln files under your
~/.emacs.d/eln-cache/ directory will be produced dynamically, when you
for the first time load the corresponding .elc file for which there's
no .eln.
