It's clearly a bug, and it's made worse in Emacs-27 where
package-initialize is called automatically before reading ~/.emacs.

IOW, I think "this" needs to be fixed before Emacs-27.1.

The fix you propose might work (tho with unintended side effects), but
I don't see any reason why we need to package-read-all-archive-contents
so early on anyway.  More specifically, package-activate-all should be
changed so it doesn't end up running package-read-all-archive-contents:
it's already the case when a package-quickstart-file is found, but if
there's no such file we call package-initialize which ends up calling
package-read-all-archive-contents even though we're only interested in
the package-load-all-descriptors part, really.
