### Typeclasses
-[HIGH] [#7916](https://github.com/coq/coq/issues/7916): Cannot set mode for `Reflexive` because `setoid_rewrite` makes some strange queries, so we suffer from backtracking and slow rewriting whenever `Reflexive ?` comes up.
-[MEDIUM] [#6714](https://github.com/coq/coq/issues/6714): `Set Typeclasses Unique Instances` does not have any (or at least not the expected) effect. Work-around: `Class NoBackTrack`.
-[MEDIUM] [#7914](https://github.com/coq/coq/issues/7914): TC resolution is unable to use the fact that `Prop` is a subtype of `Type`. Work-around: Have a separate typeclass `IntoPureT` that uses `refine` through a `Hint Extern`.
-[MEDIUM] [#6583](https://github.com/coq/coq/issues/6583): `apply` triggers TC resolution on unrelated goals so proof mode tactics randomly fail when the user has other typeclass goals open. Work-around: Use `typeclasses eauto` instead of `apply _` and otherwise `notypeclasses refine` instead of `apply`. It's hard to tell if we got this all right, though, and it may not just be `apply` that does this.

# Coq Bugs recently fixed / features recently introduced that we are not (yet) taking advantage of
* 8.16: [reversible coercions](https://mattermost.mpi-sws.org/iris/pl/yz8o9mc7apfupy7h7e3h17kqxc), see [draft MR](https://gitlab.mpi-sws.org/iris/iris/-/merge_requests/972)
* 8.20: [Smarter guard condition](https://github.com/coq/coq/pull/17986) should allow us to define `fmap`/`mbind` instances for `list` that can be used in nested recursion and do not require the `csimpl` hack.
* 8.20 [prim proj in ssrrewrite](https://github.com/coq/coq/pull/19213)
