I am aware that there's a package on ELPA, but looks like it's very
outdated.

There are quite a few differences, see full diff attached.

Probably. Gentoo also has a (rather trivial) patch that fixes some
warnings with newer Emacs versions:
https://gitweb.gentoo.org/repo/gentoo.git/tree/app-emacs/pinentry/files/pinentry-emacs-29.patch

(I still don't entirely understand why pinentry.el was dropped from
Emacs proper, but I won't challenge the decision made in bug #27445.)
