Deprecating base system ftpd?

[Ed Maste]

I propose deprecating the ftpd currently included in the base system
before FreeBSD 14, and opened review D26447
(https://reviews.freebsd.org/D26447) to add a notice to the man page.
I had originally planned to try to do this before 13.0, but it dropped
off my list. FTP is not nearly as relevant now as it once was, and it
had a security vulnerability that secteam had to address.

I'm happy to make a port for it if anyone needs it. Comments?
