These days there are too many choices for FreeBSD, you can submit a GitHub PR, Phorge PR, Bugzilla patch, Phabricator patch, mailing list patch... sharing the code is not the hard part. For NetBSD, a Gnats PR and/or mailing list comment with a patch or link is still the way.
Getting a person's attention who can and will do something is still challenging if you don't know whom, which is the same problem I saw sending patches to Linux mailing lists which went unanswered, and was given no specific feedback or path forward privately contacting the corporate maintainers.
