nit: we should sort these - I think that's the general rule for foo_switches
files. Can you fix the whole list?

But then I can't decide whether the IsFooEnabled() functions should be sorted..
(they probably don't belong in a foo_switches.h file). Appending is probably
fine for them.

Sorted these somewhere else.
