right, we have a special API to report the list of services with their metadata (this is an internal API which might disappear at some point), it would still work if you don't implement it
that is where we assign to services an "app" and an "app_type" ; only used in the UI to represent a service (the icon in the service list / the text when hovering)
So I would suggest removing the part where we create services for DD and stick to sending spans only.
