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.
