In fact, we already have the 'unexpected PLT reloc type' error so there is no
need to add a new symbol version (although the error is not clear).
So I do not really opposes it, but again the actual gain is quite minimal and a
linker that only emits IRELATIVE on .rel.plt will create binaries that only
work on very recent glibc.
