Ah interesting. The only architecture other than arm I'm interested in
is riscv. The riscv qemu port doesn't include a syscall emulation. But
I guess the riscv ecosystem still has a long way to go...

I think we can leave this concern aside as a first approximation:

The other problem I forgot to mention is that many architectures that
qemu supports don't support a "kernel emulation" but only a "system
emulation". In practice the system emulation isn't that much slower
than kernel emulation, because emulating instructions is a lot easier
than emulating syscalls

Yep, thanks! =)
