The last ebuild that was from < 5.32 was dropped in February via https://gitweb.gentoo.org/repo/gentoo.git/commit/?id=2a5e53723dc747c2175b5649431a357cf1d80574

This can be closed now.

Yes - although we still need to decide if it merits a GLSA (we're rather behind and catching up atm).

Most ReDoS isn't GLSA worthy. All done.
