I'd like to be able in #nasqueron-ops to enable or disable dangerous changes with something like .repo rOPS dangerous on

That could use:
https://devcentral.nasqueron.org/conduit/method/diffusion.repository.edit/

Or as the worfklow is to delete remote branch we could have something like: .-branch rOPS <branch name> that would enable dangerous changes, do a git push --delete and then disable dangerous changes.
