But one thing I'm not sure about is whether IO_PGTABLE_QUIRK_ARM_OUTER_WBWA is something that other devices *should* be using as well, but just haven't gotten around to yet.

The intention is certainly that this would be a place to collate per-domain pgtable quirks, so I'd prefer not to tie that to the GPU.

So the overall consensus is to just keep this as-is for now?

Yes, please. If it doesn't see wider adoption then we can revisit it.
