Many people think that for later reference a history where each commit contains exactly one feature or bugfix is more useful than the usual development workflow of "start feature a, fix bug in related feature b, fix documentation of unrelated startup flag, implement feature c that turns out to be prerequisite to feature a, do more work on feature a, fix bug in c, [...], finish work on a".

And in case you want to commit to an open source project you are basically forced to rewrite history for any non-trivial change because changes that make sense to develop at the same time often form independent PRs.
