That's down to culture and (self) discipline, not tools.

It's not entirely, because Github simply does not support inter-version diffs when you have multiple commits. If you force push onto multiple commits there is no way to show a diff between version 2 and version 3 of those commits. How Github lacks such basic (and imo necessary) functionality in 2025 is amazing to me.

Something like linked and dependent PRs in a chain would go someway to replicating Gerrit but again this basic functionality is not available out of the box for whatever reason.
