One (narrow) circumstance to make the process of reviewing a large contribution — with significant aid from LLM — easier to review is to jump on a call with the reviewer, explain what the change is, and answer their questions on why is it necessary and what it brings to the table. This first pass is useful for a few reasons:

1. It shifts the cognitive load from the reviewer to the author because now the author has to do an elevator pitch and this can work sort of like a "rubber duck" where one would likely have to think about these questions up front.

2. In my experience this is a much faster to do this than a lonesome review with no live input from the author on the many choices they made.

First pass and have a reviewer give a go/no-go with optional comments on design/code quality etc.

Have you ever done that with new contributors to open source projects? Typically things tend to be asynchronous but maybe it's a practice I've just not encountered in such context.
