FYI, this 'mere' kind of indiscriminate definition of 'breakage' is what i am
talking about.

The occasional driver build breakage can be tested relatively easily: one
allyesconfig build and it's done. Build testing 22 architectures is
exponentially harder: it requires the setup (and constant maintenance) of
zillions of tool-chains, plus the build time is significant as well.

So this kind of linux-next requirement causes the over-testing of code that
doesnt get all that much active usage, plus it increases build testing
overhead 10-fold. That, by definition, causes the under-testing of code that
_does_ matter a whole lot more to active testers of the Linux kernel.

Which is a problem, obviously.
