Hardly anything modern about it, but it's a way of keeping a somewhat sane history. Certainly better than merging 'fix' 'fix' 'fix comments' into master.

The thing is, we could have done better (and have been) since before git even existed.

The "squash everything" mantra turns git commit history into a series of snapshots devoid of any logical notion about how code evolves.

Squashed commits are strictly worse than plain, non-fast-forwarded merges from rebased branches.

There are legit reasons to have a series of commits within one PR, and rebase and merge them as is, and use amend/fixup and force pushes to maintain them cleanly.

It's not my favourite process, but...
