I'm at 25 at the moment, suprisingly all of them so far are a syscall
with a few parameters, sometimes packed in a struct.

I guess that we can, but we would have to add some private data area to
the tst_fd, so that we can tear down things cleanly, but we would need
that if we want to convert the tst_iterate_fd() to be iterator-like
anyways.
