>In larger projects, a single commit is rarely pushed alone.
When I say a commit message, I mean the thing that ends up in the source history when the change is merged. So if you're doing squash and merge, then the commit message that matters is the PR title + description.
For teams that just merge everything including commits like "wip" and "address notes from code review", their commit history is a mess anyway, so they have bigger fish to fry.
