What I think I see these days is squash merges being used lazily to avoid having to do anything to build a clean history with clearly semantically delineated commits. Squash merges are good compared to an alternative where people check in super messy noisy branches, but they unfortunately have a big downside because squash merges can make bisecting and history spelunking more difficult, when the branches that are squash merged were big.
