• 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.
