Great news!
Before I made a list of the packages that use camlp5 still - in case anyone wants to try them with a new version:
- ELPI (there is an issue to drop Camlp5 support https://github.com/LPCIC/elpi/issues/13 )
- bigbro
- ledit
- orpie - https://github.com/pelzlpj/orpie/issues/18
- ulex-camlp5 (deprecated in favor of sedlex)
