If you are doing a good refactoring, you may have a massive negative LoC at the end.

LoC added or removed is not a very good metric for anything.

Except if I see a big negative number on a PR, it is usually a great thing. I still have to check what was removed but it usually mean that things are easier to understand.

Anytime I see a good chunk of redundant/useless code removed, it's a good day!

The greatest, most joyous programming is deleting large chunks of code.
