I haven't actually looked into this part of the patch, since as far as
I'm concerned this patch is broken.

Having said that, if using a second Kconfig symbol is worth the effort,
perhaps there's also enough reason to break Kconfig backward
compatibility. People shouldn't alter Kconfig symbols just because they
can, but as far as I'm aware we're on the record to not guarantee
backward compatibility for Kconfig symbols.
