IIRC there are a few DRM and anticheat systems that use syscalls directly,
apparently RDR2 does as well
(https://github.com/ValveSoftware/Proton/issues/3291#issuecomment-562993403).
While I agree that this is crazy, I don't know if there's any other way. That
being said, I don't believe wine necessarily needs to switch internally to
using syscalls instead of IPC, "only" support syscalls as well, so the
performance or compatibility impact for any application not using syscalls
directly (i.e. nearly all of them) shouldn't be affected.

Is there an issue with seccomp? I've used it in the past, and while at the time
it didn't support what I was looking for (passing fds, although the one who
posted the patch was interested in pursuing this at the time), it was quite
easy to use and as far as I could tell, there wasn't much overhead either.
