> “I’m going to do X in 5 days if you don’t respond” gives you absolutely no recourse if you do something that can result in reprimand.
Surely you wouldn't use this for any action that could result in a reprimand?
"Unless we receive objections, we're dropping the domain $X on March 1st and switching to the domain $Y instead" is not something you'd do.
OTOH, "Unless we receive objections from you, we're proceeding with (the current mocked-up UI|the last discussed tech-stack|deployment date|refactor|)" is not going to result in a reprimand.
