Conversation
Now that we're using a type folder, the arguments in predicates are processed automatically - we don't need to descend manually. We also want to keep projection clauses around, and this does so.

why did you open this as a separate PR rather than let me just rebase #123045? lol |

Now that we're using
TypeFolder, avoiding the instantiation at identity and keeping theProjectionclauses is as simple as not transformingty::Dynamic- the folder will recursively visit the args for us where needed.This is intended to have the same effect as #123045
This is currently on top of #123521, but if it appears that won't land, it can easily be rebased onto master. Setting as draft until #123521 is merged or rejected.
