Initially we could keep these matters orthogonal.

We could always (not as an option) keep actively probing things we
observed. In other words, if we saw something on an address, it's on the
observed list, we could ping that once a day. If its not seen for seven
days, we could drop it.

That's independent of HOW we observed something in the first place. If
we are passively watching, and we see something, it's on the probe list.
If we are allowed to actively watch, and we see something, then it's on
the same probe list.

Would you have any objections to pinging something we observed, once a
day? That seems much less contentious to me than an active scan of a VLAN.
