I think it is too late for GCC 11 for this.
Especially if the solution would be that we change the behavior of existing
attribute, we would need enough time to test everything in the wild that
we don't break it badly, even if we add new attributes that cover the
previous behavior.  Only if we keep the behavior of existing attribute
and add a new one with the new behavior it would be something that could
be considered for GCC 11 IMNSHO but then you'd need to change the glibc
headers in time too to buy into the new attribute.
We need analysis of all GCC targets with target attribute support and
handle them consistently.
