A bit of an aside, but it would be incredibly awesome if the FreeBSD
port could adopt the same policy as, eg, Debian and not ship any
patches that are not upstream.

We do consider such patches, with justification, when submitted by or
on behalf of their authors.  See for example this recent MR submitted
by Debian: https://gitlab.com/samba-team/samba/-/merge_requests/1420

It makes assessing issues like this much easier.
