Duck/cancel and green server

Since the devs have already implemented the code for it, my guess would be that Green won't allow ducking until it's era-appropriate.

But really we're all just idly speculating for no reason, which does no good because it's not like we can reason or discuss the answer out: it's entirely a matter of staff preference whether any given non-classic quality of life improvement will make it to Green (and in a relatively short time they'll answer all these questions).
