They will not vanish. They are there to map git commits back to SVN
revisions.
What will change is that they'll never change again and are just a static,
eternal record
of that mapping.

Of course, freebsd committers can then in the future push their own notes
(but not force-push them) , but it's not clear what you would want to put
into them?

If you don't have a need to ever map git <-> svn commits, then you don't
need to fetch
them indeed.
