I don't think the "object format abstracted" flags have a very well
defined meaning and don't get a lot of use. Since you are one of the
few users, feel free to refine them.

The output format of llvm-nm and llvm-objdump is pretty locked given
that we want them to match the native nm and objdump.

It could be done in llvm-readobj, but that one is designed to dump
pretty much everything, so it is format specific.

llvm-rtdyld seems to be the winner.
