I don't think this is an appropriate use of "just". If io_uring doesn't work with seccomp-bpf filters today, there are many situations where you just can't use it, period.

That someone with kernel IO dev experience may be able to relatively easily add such a fetaure in the future (though I would doubt that, given that it hasn't yet been implemented apparently) doesn't make it a small problem.
