MIPS GOT has some advantages for MIPS hardware. Making it more similar
to other GOTs is not a clear decision which provides only benefits
without any disadvantages.

In general, if we do not support current MIPS ABIs in LLD, nobody will
use LLD for MIPS. If nobody use LLD for MIPS, any attempts to discuss
/ invent / improve MIPS ABI will be useless. From end-user points of
view there are bfd/gold linkers support all MIPS specialities and it
is not clear why the end-user needs to accept or even waste a time to
discuss one more MIPS ABI just to start using LLD.
