This policy may not apply here.  It's applicable to "larger"
chunks of new code, like complete drivers or complex features.
Not everyone wants support for unused features in their
executables that need to fit in constrained resources.  That's
well understood.

Your case is different.  There is a feature, it's already present
and small and unconditional.  And your change even shortcuts this
small portion.  I guess that adding another compiler switch for
this may not be appropriate.

But let's see what others have to say.  I'm not an expert in
policy.
