Brainstorm-to-improve-UX: Ever since migrating to mempool based sequencing with 0.14, I get gentle vibes of unclarity around what transactions are in the mempool and when to resend transactions (assuming no fee escalation is desired). Specifically, transactions may silently drop out of the mempool when there is congestion without any notification to the sender. Is this something you suffer from? Any recommendation or reference to a DECENTRALIZED chain that has a nice solution for this issue? For example, the team could externalize status of transaction in the mempool from one random node but this will not is a future-compatible solution because when there is a decentralization each node may implement its own dropping policy. (And even short-term there could be short differences between expiry on different nodes that can lead to inconsistencies)
