In my experience, the resistance to rebasing comes down to fears about "rewriting history" [...]
There is 'git bisect' which only gives you detailed answers if your commit history is as fine-grained as possible while still being compileable and testable. Also, changing commit IDs on branches that are visible to others are a problem.
Which is why my approach is as follows: Work on private branches, one per feature/fix/..., then do interactive rebase to create a compilable and testable patch series out of those onto a for-review branch. While developing, rebasing onto whatever public branch you want to merge with next is of course OK and necessary. When you think the feature in the for-review branch is ready, do a merge-request into the public target (mostly devel) branch as usual, and either merge or rebase, whatever you like best.
But: Whatever branches are public are only ever merged. Never squash-merged, never rebased, never force-pushed, never filter-branched (except maybe after a court order). Because all commits on those branches are necessary to trace what people were doing with the code. All those commits and their relations are necessary for git-blame, bisect, sloccount and other things. Any commit ID there could wind up in some test binary, release ID or stuff, and you absolutely truly need those later on. And while a simple rebase might keep some of the necessary details intact (the other branch will still be there after all), only a plain merge will also preserve all the relations between the branches properly.
