AFAIK `elpa-admin.el` is mostly used with "Emacs from Debian stable" (in
`elpa.gnu.org`) and with the bleeding edge of Emacs, so backward
compatibility is not very important beyond Emacs-28 now.  The one you
see is what was added at the time and simply hasn't been removed (yet).

Usually in the context of macro expansion you can use `eval` for that.
Here we don't, for (arguably bogus) "security" reasons.
