If I have more commits related to more revisions in a single branch, I would like to use arc land to land all or some of them.
Ideally, arc land should detect that there are more landable revisions in the branch and amend all of them before pushing.
I should also be able to land only some commits with something like this:
$ git rebase -i pick a x arc land --keep-branch pick a

| Resolved | epriestley | T3875 Allow arc to perform cascading rebases, maybe during or after `arc land` | ||
| Resolved | epriestley | T2493 Support `arc land` in stacked commits |
I have a mail thread somewhere that I'll paste in here eventually.
(My sort of meta-stance here is that stacking changes in a single branch is a weird, Facebook-specific workflow that's not very good, and that the only advantage it has is that you can rebase everything quickly; implementing a cascading rebase and then pushing for a multi-branch workflow might be a better approach in the general case. But there's no real reason we couldn't do better in arc land too.)
This general issue receives significant discussion in T3875. I don't think we've seen significant adoption of the unusual "stacked-on-the-same-branch" workflow, but similar concerns apply to branches-on-branches at the least.
