Kees have been always against using ebpf in seccomp. I believe he still
holds this opinion. Until he changes his mind let's stop bringing
seccomp
as a use case for unpriv bpf.

That's why I said "whether or not".
For the record, I do prefer a non-unpriv-ebpf way.
It's still something that will most surely come up in the discussion though.

It's very un-kernely way to defer to in-person meetings.
If there is anything to discuss please discuss it on the public mailing list.
