perl compatible regexes in grep have always been "experimental"
and never officially supported.
From the grep manual https://www.gnu.org/software/grep/manual/grep.html
--perl-regexp
Interpret the pattern as a Perl-compatible regular expression
(PCRE). This is highly experimental, particularly when combined with
the -z (--null-data) option, and ‘grep -P’ may warn of unimplemented
features. See Other Options.
It wasn't dropped so much as "enhanced" away.
Oh well.
