You squash so all your gross “isort” “forgot to commit this file” “WIP but I’m getting lunch” commits can be cleaned up

The next step on the Git-journey is to use interactive rebasing in order to never push these commits in the first place and maintain a clean history to be consumed by the code reviewer.

Squashing is still nice in order to have a one-to-one relationship between commits on the main branch to pull requests merged, imo.
