Sure.

Wow, ambition!  I like that.  :-)

What is the logical next step of a transition strategy here?  I don't
want to have abrupt changes that break things, but issuing warnings
should be OK.  For example, what happens now when people assume that
--host sets --build?  (Sorry, I don't do cross-compiles much, so I'm a
relative novice here.)  If it doesn't generate a warning, perhaps we
should just generate a warning for now.
