Ah, I wrote it like that after Marian's comment here: https://github.com/llvm/llvm-project/pull/182410#discussion_r3009643797|

where he said: "this operand is basically XSeqPairsClass + [XZR, XZR] and you need to treat it as such. If this approach works, I think we will also not need custom printer, assembler etc... but can reuse the ones from XSeqPairsClass with maybe minor modifications"

So you are asking for custom printer/decoder, and Marian says we will not need a custom printer/decoder. I don't mind which approach we take, but I've already switched it once.
