Is there a particular reason why not all party submission functions also exist for users?  
(For example `submitUserMustFail`)

When it comes to `submitMulti` I’m assuming that the argument would be to just add the additional actAs/readAs parties to the user, but I don’t see an easy workaround for `..MustFail`, except to use

```haskell
(fromSome myUser.primaryParty) `submitMustFail` ...

```

The same question also holds for queries

There is no good reason, we just started with the minimal API. However, `submitUser` is just a wrapper, you can see the definition in the [code](https://github.com/digital-asset/daml/blob/74b7878d6ec77080681f09310e299f54ea752371/daml-script/daml/Daml/Script.daml#L953).

You can relatively easily define your own wrapper for `submitMultiMustFail`:

```haskell
submitUserMustFail : HasCallStack => UserId -> Commands a -> Script ()
submitUserMustFail userId cmds = do
  rights <- listUserRights userId
  let actAs = [p | CanActAs p <- rights]
  let readAs = [p | CanReadAs p <- rights]
  submitMultiMustFail actAs readAs cmds

```
