Why? I do this sort of technique all the time at work to keep things moving. “I’m gonna ship this code on Friday and if I don’t hear anything before then I’ll assume no news is good news and do it!”.

There should always be an upper bound to how long somebody can block your progress. If something was so important that they want to block me, why didn’t they tell me before Friday? That was ample time to raise objections.

It’s just an SLA and holds people accountable.
