There's a spectrum, right?

On one end of the spectrum you've got presumably you, who brings a sketch or prototype to engineering, and has a reasonable discussion about what can or cannot be made production ready on what timeline, with what budget.

On the other end you've got people who bring a half baked prototype to a couple engineers, demand it be in production next week, and then escalate and make a big scene when there's pushback.

No engineers tend to complain about the former. The latter is stressful as hell
