The flag is not restricted to the C++ compiler and applies to all automatic variables.
This only affects the clobbers for C++ temporary objects, not clobbers for automatic variables going out of scope.

A more "proper" place to fix this is when we actually do the stack reuse, in cfgexpand.
How would that distinguish between the clobbers for temporaries vs. automatics?
