I believe the default should be to generate the additional new unwind
information. The only people who would not want it would be people who
want to minimize their binary size. I also don't think this has
anything to do with --eh-frame-hdr, which simply directs the linker to
create a PT_GNU_EH_FRAME program header. So I think there should be a
new linker option to *not* generate unwind info, and we should have
-fno-unwind-tables pass that option to a linker which understands it.
