Trying to maintain something that works across more than 3 releases or
so is painful. I don't think android-x86 folks have the bandwidth to
maintain things older than that *and* update to newer versions. So I
think only supporting the n latest releases is good.

Are .bp files for master/Q compatible back to N (or O)? IIRC, at least
for the first couple of releases with .bp files, they seemed to have
incompatible changes.
