The cosmos-sdk branching is a mess. Where is this commit 6e569e125571 from?

https://github.com/cosmos/cosmos-sdk/releases/tag/v0.40.0-rc1 is 68a23c4, which would probably be the best to target now.

We cannot follow master (which may have non-0.40 breaking changes in it) and can only follow commits on release/v0.40.x branch (which luckily contains both v0.40.0-rc0 and v0.40.0-rc1).

[ethanfrey]

Ow. "Refactor x/{gov, crisis} according to ADR 031". Yeah, this is Aaron's breaking change he is planning for 0.41.

You can only trust tagged releases. Never trust master. I am afraid you will have to redo a bit of this PR with that in mind. Hopefully not much 🙏

[ethanfrey]

Okay, I pulled back on the cosmos-sdk commit and got this compiling with v0.40.0-rc1. I did no manual testing beyond make test and make build, but used simapp as a reference to resolve any compile issues

[ethanfrey]

Looking good.

A bit of cleanup on the handler plugins, but generally ver nice job with this 🥇

I would like to fix codecov or remove it (it seems rather useless and non-deterministic). But that is for another PR. Let's get this in 🚀 🚀
