perl compatible regexes in grep have always been "experimental"
and never officially supported.

    --perl-regexp

    ÂÂÂÂInterpret the pattern as a Perl-compatible regular expression
    (PCRE). This is highly experimental, particularly when combined with
    the -z (--null-data) option, and âgrep -Pâ may warn of unimplemented
    features. See Other Options.


It wasn't dropped so much as "enhanced" away.

Oh well.
