If we only tracked the target amount of peers per network, we'd risk being eclipsed by an
adversary who immediately connects to us with their array of validators upon our boot. Their
array would satisfy our target amount of peers, so we'd never seek more, enabling the adversary
to be the only entity we peered with.
We solve this by additionally requiring an explicit amount of peers we dialed. That means we
randomly chose to connect to these peers.
