I agree that MIPS is unusual architecture from the linker point of
view. But other linkers like gold and mclinker have not too
complicated design, fast and support MIPS together with other targets.
I do not have ready solution for LLD but maybe ability to create
target specific GOT sections, override iteration over relocations etc
allow to isolate unusual MIPS code and does not pollute common code.

Sure that does not mean that I like current MIPS ABI :)
