I hope the submitter is also aware of https://portscout.freebsd.org/ ?
This type of PR is against the guidelines: https://www.freebsd.org/doc/en/articles/problem-reports/pr-when.html specifically listed as not appropriate: "Notification of updates to externally maintained software (mainly ports, but also externally maintained base system components such as BIND or various GNU utilities)." If you had a patch to update it along with proof of basic testing, that would be appropriate. Feel free to reopen when you have such a patch.
