Is there a way to disable this feature? Our security team has noticed that with this feature we can land code with just a single person's machine being compromised (we rely on an attacker needing two machines to deploy code as a safety mechanism). I.e. You make a revision, Foist it on someone, Approve it, then arc land it as the other person (saying y to the prompt).

This part may prove slightly trickier to implement correctly in the general case.

+1 for this command. We have use a web-based UI for landing so our branches stick around locally. To fix this I'm currently using:

arc branches | grep ' Closed ' | sed 's/[^ ]* //' | sed 's/ .*//' | grep -v master | grep -v '^[0-9a-f.]*$' | xargs git br -D

How did you fix this problem?

@epriestley I'm totally with you, we don't want any special casing for Facebook. I was just hoping others could benefit from this as well.
