I can (partially) speak for powerpc.  If ARM uses this approach, then
I think we can do the same.  After the defconfigs are trimmed, I
certainly won't pick up any more full defconfigs.

Of course, I'm also operating under the assumption that this is a
temporary measure until one of the better solutions is implemented.  I
do suspect that the trimmed defconfigs will tend to be unstable and
will still require manual maintenance.  I think the Kconfig fragments
approach is the most promising if the dependencies issue can be
solved.
