Right.

Do you think we can generalize it to a DUMMY frontend where some fields
are just queried ?

If so it would be a matter of just defining a "dummy name" for the
general category of headless devices where some statistics can be
queried. Or do you think it would be right to have it called as DVB-ASI
frontend itself ?

(In my thoughts it would be incorrect probably to call it DVB-ASI, since
DVB-ASI doesn't get specified as a delivery system as defined by a
frontend, but just as a transport method only)

But in that case each of those headless devices will need to have a
specific name. Though not too many headless devices come to my mind though.
