We already got that possibility for free along with src/Makefile.inc1#1.590,
so no particular efforts are needed to support it.

It's an exaggeration.  The most of /usr/[s]bin aren't in /rescue yet. :-)

One of the things I love FreeBSD for is being able to do things in
different ways and to choose such a way depending on the case. :-)
E.g., one may want to go from CURRENT/arch1 to CURRENT/arch2 without
having to install a binary release or snapshot for arch2 first.
