I agree with Tony about what should happen, but I would express it
differently.

I think the exploder/relay should decide whether tracking occurs beyond it
(probably applying Tony's algorithm). At the very least this is necessary
for reasons of the privacy of the subsequent recipients.

So there needs to be an architectural mechanism for tracking beyond an
exploder/relay, but unless something actively permits it then it should not
be visible.
