A lot of people are religious about rebasing, "clean" commit history. But it's pretty much incompatible with several devs working on a single branch. I.e. when you work on something complex, perhaps under time pressure, git habits bite you in the ass. It's not fine.
For larger features we often have a feature branch with merge requests for various task branches. Limits the review sizes as well.
Of course, you can also then consider to use feature toggles, so there's no feature branch but just your main branch.
Years and years ago I worked on a team where linear commit history was required so every time a merge happened you had to manually rebase and push to Bitbucket. I put a PR in halfway through the sprint, rebased it a dozen times as everybody else's work got merged, and had nothing to show during review because nobody bothered to check mine and the only coworker I had in the same physical office was out on vacation.
When I interview for new roles I always make a habit of asking how work gets done to avoid shops that engage in these types of shenanigans.
bitbucket will merge a PR from your feature branch onto the base branch even if it's not fast-forward from the base branch. as long as you use the "squash" or "rebase" option on the PR interface (instead of the "merge" option), the resulting history will be linear
