FWIW, {e,f}grep have been reintroduced in Debian with grep 3.8-2.

Now, the stray \ warning is causing trouble. libtool has a problematic
grep \-L:
https://sources.debian.org/src/dpkg/1.21.9/m4/libtool.m4/#L6472
which is embedded in an important number of packages:
https://codesearch.debian.net/search?q=Configured+with%3A%22+%7C+%24GREP+%22+%5C-L&perpkg=1

Jochen Sprickerhof has already reported the problem in libtool,
including a patch:
https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=1019725
https://lists.gnu.org/archive/html/libtool-patches/2022-09/msg00001.html
but it will take a lot of time before all of the concerned packages get
a fixed libtool.

I am willing to temporarily silent those warnings, once the affected
packages have been identified, so we can submit bugs and fix them.
See: https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=1019724

Cheers,
