As someone who does maintenance instead of new feature development: you're right. Squash merges are totally useless. I always want the real history, which lets me see when during the feature development the bug was actually introduced, and the original commit timestamps, which I can correlate to comments on the case.

There is never reason to squash. The best of both worlds is to always force a merge commit (disable fast-forward merges) and look at the log formatted whichever way you want (--first-parent shows people that linear history without destroying history).
