I agree. If the solution is to invoke c++filt, that could be invoked
just as well by the g++ driver, or collect2, or even by the user -
there is no need for libiberty creating new processes.

Adding new demanglers to -liberty is the right thing, IMO. However, I
dislike dynamic loading of them - this is an additional step that can
fail. You cannot easily move ld or gdb binaries around as you
currently can. The political issues of such extensibility are also a
strong reason for me to dislike it.
