Double deploy when --force is enabled

[namoscato]

Is there a reason deploy() is initially invoked with dontuseforce: true?

When --force is enabled (dontuseforce: false), the initial deploy() is expected to fail before a second --force attempt, doubling the end-to-end time of the actual deploy.

+1 for this. Would be awesome if we would be able to enforceforce :)
