I'm not sure if that's related, but since it's now possible to wrap playwright commands with test.step(..., {box: true}) to encapsulate and combine steps, it could be nice if the route.abort, route.fallback served-from-har and other routing related things will be aggregatable.
in our tests we have lots of route.continue noise
