KIP 21 also reduces Proof of Acceptance receipt size to "lane activity".

You want to prove your transaction was accepted, but it has been pruned?

You save a receipt that cryptographically proves the tx you provide hashes to a preserved forever pruning point.

Newest article this week, about KIP21.
