- `arc land` should respect the tracked branch when choosing an `onto` branch, if one exists. This should have weaker strength than `--onto` but be stronger than `arc.land.onto.default`.
- `arc land` should respect the tracked branch when choosing a remote, if one exists. This should have weaker strength than `--remote`.
Possibly we also need `--remote-onto` if you want to land `local/branchA` onto `local/branchB` and push it to `remoteC/branchD`, but this is pretty silly. You can use `--hold` and then execute the push yourself if you need to do this, and I don't think any users have actually hit this yet.
