This repository is purely experimental. It is meant to track cross-stack issues. These are issues which we do not know where they belong (is it a Tendermint? an SDK? an IBC-go problem?) or which have multiple dependencies in different repositories, potentially across multiple organizations (cosmos, informalsystems).
This issue is a difficult one, because there is a lot of unclarity around it. It has dependency on ABCI++, Tendermint, SDK, and relayer. It should be designed and implemented as a product feature having the users in mind first.
The SDK plans to work on nonce lanes in 2023, according to their 2023 plans. A technical reference is here: https://github.com/cosmos/cosmos-sdk/issues/13009
