... which does not seem be doable when the fs is mounted:

[in single-user, with only / mounted r/w and /dev]
# geom label label root /dev/ad0s1a
geom: Can't store metadata on /dev/ad0s1a: Operation not permitted.

Unfortunately, I do not have physical access to the machine. I guess
that transition will be a royal PITA for a lot of people.

Btw, you mentioned "device", I guess you meant "file-system", didn't you ?
