Force-pushing is one thing, but projects that squash all PRs in an act 
of truly evil stupidity (looking at you, CPython) will undercount 
changes, since what would be a series of changes in OpenStack or a PR 
with multiple commits in another project ends up as a single commit.

That GitHub (and GitLab, who came up with it first) forces you to choose 
between squashing independent commits in one PR or not squashing the 15 
"fix tests" commits in another is a prime example of what makes it an 
awful tool for code review.
