Is this a bad thing though? If some technical decision has downside risk, I’d reasonably expect:

- the affected stakeholder to bring it up

- the decision maker to assuage the stakeholder’s concern (happy path) or triage and escalate

I think you are right. It's still worth encouraging people to question decisions even though most of the time it won't be the right compromise for the business.
