You specifically mention "big feature" in your original comment so it's confusing that this is a good example of the kind of problem you're talking about.

This is a very different situation than large PRs containing feature code. I think most people would agree that one large PR is the correct approach for this kind of situation.

Usually new features require modifications of old code, at least in my experience. If I came across as claiming it's likely for a feature to require 5k new lines of code, then I clearly communicated badly. But a feature coming with 5k lines of modified code, while rare, still happens several times a year in a large project in my experience.
