At my last job, the workflow was mostly merge based instead of rebasing. After you create a branch, you merge from develop of there’s anything new you want or to resolve conflict. And the whole PR will be squashed and merged (there’s an ID referring to the ticket). Force pushing to an open PR was frowned upon.

I think it reflected the email based approach a bit better as you can’t alter the first patch you sent, only send new ones. So even if the history of a PR is messy, we preserve its chronological aspect alongside the discussion.
