Yes but one could also reasonably argue that TestFlight apps are downloaded from the (wait for it...) TestFlight app and should be combined. Just going by the meaning of a utility, any app can be categorized as a utility, really.
So, I'd guess that it's up to Apple and the developer (in the case of the TestFligt app, that's Apple too). If you must complain, complain to them. We cannot change it.
