You’re not an example of what we’re taking about here. Congratulations!

A better example would be if you’d changed the behavior of the library as you did this work, and the library changes introduced hard-to-detect bugs across the application.

Yes exactly. the GP isn't what we are talking about it and huge PR isn't what we are talking about either.

PR can be huge that's OK. For example, codebases that moved from Python 2 to Python 3 would have had huge PRs but the cognitive load was well understood.
