I agree.  But realistically, changing arcane things affecting
compatibility of existing code bases is nearly impossible.  It's far
more tractable for those who really understand the issues and are
using the features in new code to use the new switch explicitly, and
for people defining new ABIs without legacy compatibility concerns to
make the compiler driver pass the better default to the linker
implicitly (as we will do for Fuchsia).
