Can you explain why it's necessary that some notifications were dropped?

2 reasons.

- To avoid OOMing the Erlang VM. - If the notification queue is backed up then older notifications are not worth delivering if we can speed up delivering of more recent ones.

Except that's not what's happening here if I'm reading right. They are throwing away the newer ones and not the older ones because the ones rejected by the Push Collector are the most recent ones.
