I think this is not a good idea, at least for the moment -- I doubt many
developers can even attempt to test that -current will build on all
supported target systems. Giving a developer hassles and negative
feedback just because they broke something they can't even test is not
someting I can condone.

Well, yes, tinderbox *might* make such a rule more "acceptable", but
indeed what's really necessary is a full cross-compilation system and
totally self-supporting build system (as I outlined a little while ago,
based on your and other's previous ideas). Building "bits" from scratch
is not sufficient -- they must be built on a cross-compilation system as
if they had been built on the target system -- and the final result must
be byte-for-byte identical (sans timestamps, etc., of course).
Of course since this is a full operating system, not just a user-level
application, there's also the issue of basic kernel fuctionality -- and
testing this really does require a regression testing harness that'll
support autonomous control of a remote hardware test platform.
