At least with my experience at amazon it wasnt.

if i wanted, i could queue up weeks worth of review in a couple days, but that's not getting the whole team more productive.

Spending more time on documents and chatting proved much more useful for getting more output overall.

Even without LLMs ive been nearby and on teams where review burden from developers building away team code was already so high that youd need to bake an extra month into your estimates for getting somebody to actually look.
