It's a different kind of fragility, things break immediately when you
add something new which is reasonably obvous as opposed to happening
at some other time due to a tooling issue and what I'm concerned about
avoiding.  In any case...

...Linus already merged my alternative patch which does this with a
select..if which never seems to have these issues.

Your patch *should* work but due to past issues and the fact that I can
understand why they might occur (the semantic of select is "just enable
this" which doesn't pay too much attention to the target) I'd rather go
with this different approach.
