Debian continues to make security/maintenance patches to Procmail:

https://metadata.ftp-master.debian.org/changelogs//main/p/procmail/procmail_3.22-26_changelog

So, I hear of lots of people still using it on Debian and derivatives.
But yes, avoid excessively old/unpatched versions of Procmail.

Maildrop is a popular alternative.
