I have a patch that I'll send soon to make x32 use its own table. As far as I'm concerned, 547 is *it*. 548 is just a normal number and is not special. But let's please not reuse 512..547 for other purposes on x86 variants -- that way lies even more confusion, IMO.

Just so I understand: do you mean duplicating the .tbl file, or just the resulting table of entry points?
In either way, how will that work with the new io_uring_setup() system call that will have to use the compat entry point? Are you planning to use the same syscall number as x86_64 but point it to the compat function, or do we still need a new syscall number for x32 in the regular range?
