I am totally going to advocate for this at my workplace. I myself am guilty of it - not saying "just", but questioning people's estimates based on my limited understanding of the research they had to do to come up with the estimates in the first place.

It sounds pretty toxic if you're not allowed to even question other people's estimates. IME that's a large part of Grooming/refinements

Aiming for an environment where uniformed challenges to estimates are discouraged is an entirely different thing to forbidding any challenges to estimates.
