| I can add a test for it, comparing old parent identifier with p_ppid

That would be useful, I suspect they will be the same except when the
process is being traced.

| The 4th field should be PPID.
That one comes from p_ppid .. so will also probably be (currently) incorrect
for a traced process, so a test would be good to verify. That could also be
fixed by using the new kern_getppid() or by just not changing p_ppid in
proc_reparent() if no-one can find a reason why the change is needed.
As best I can tell, p_ppid is used excludively for providing info to userland,
and the info wanted is always the original parent's pid, so changing it
doesn't make a lot of sense to me.
