They aren't noise at all and have found them useful a bunch in the past when I worked at a place that didn't squash. Commits at this level act as immutable comments that don't get out of date. Provided you do --no-fast-forward merges, the merge commit is the feature commit and you can get the "clean" feature history with `git log --merges --first-parent`. Best of both worlds! Being able to `git blame` and get a granular message about why something was done can be really handy, especially when looking unfamiliar code.
