s/wouldn't want/*can't* by design have/.

i don't know that running under rump is useful here.  i certainly
would not trust ptrace tests in a rump to cover it properly.  this
test should just be skipped if securelevel >= 0.  fact is that
very few systems run with securelevel these days, so it's a small
portion of systems that won't have it.
