I agree with the general approach.

I suspect a common case where people hit this is something like 'make
&& sudo make install' which can end up with some files being owned by
a different user.  In a sense they ought to fix this but perhaps many
people would prefer to just have some stuff uncached.

I would be inclined to at least give a suppressible warning rather
than just silently falling back.
