Its commonly understood that whoever is reviewing the PR shouldn't concern themselves with all of the project’s context (business or any other).

It really takes a glance at the PR to see what the author wanted to create and you can pick up on bad directions the AI took and so you just help the person navigate these choices.

Of course if the project has to actually grow into a product at some point you would have to rewrite good chunks of it.
