Well, if no general-purpose usecase can be defined, it yes, makes sense
to just set app_ad and info to blank unless application uses those for
something (there is already stuff with similar interop impact in
RFC8152).

However, the part where by-default blank ad and info is specified
could use some word-smithing to avoid misinterpretations similar to
mine.

I changed my test implementation to pass empty info (the app_ad was
already empty).
