lol. the whole easily reversible (or two way door vs one way door) sounds soooo good in theory. You know what? Everything is reversible. The question is not how reversible it is. The question is how much effort does it take.
also, people use "bias for action" as an excuse to basically do the first thing they can think off. When you push back they will want you to "disagree and commit" and after that when something, anything is delivered the same ppl are gonna claim they were right. In fact they are "right a lot"
