https://github.com/ethereum/consensus-specs/pull/3360 effectively
extends the valid lifetime of an attestation/aggregate to 2 epochs -
this means that an aggregate that was published at the beginning of a
slot now is valid per the gossip rules up to 2 epochs later.
Then net effect of the above change is that peers are allowed to
republish old aggregates and attestations and libp2p will not stop the
spread with the settings we recommend - instead the messages will have
to be stopped with the "attestation cover rule" or similar, even though
they have been observed already.
Significant amounts of this kind of spam have been observed on the
aggregate channel in particular leading to a 5x increase in aggregate
traffic as some clients republish these old messages in spite of the
"attestation cover rule" which should have stopped them - this simple
change will provide an additional layer of protection against such bugs.
