Yes.  Porting from Emacs's master to our maint branch has been on hold
leading up to the Emacs 27.2 release to avoid any syncs carrying those
commits into the emacs-27 branch [1].

  [1] A list of those commits is here:
      https://git.kyleam.com/orgmode-backport-notes/tree/orgmode-backports.org#n62

The fix you're referring to on Emacs's master branch 5ada3eecec
(lisp/org/org-refile.el (org-copy): Fix missing obsoletion version,
2020-12-17) is in these held commits.  However, I wasn't yet aware of
the more recent commit associated with the message you quoted above:
32c6732d16 (lisp/emacs-lisp/byte-run.el (make-obsolete): Make `when`
mandatory, 2021-01-03).  That makes it important to apply 5ada3eecec to
Org's maint for compatibility with Emacs's master branch.

Indeed.  Ported (248dfcd71) and moved (33de2bd8e).

Thanks for the heads up.
