Sources for AcoustIds with only User Submitted Data

#1

I was revisiting how I use AcoustIds and I noticed that fingeprints with user submitted data, also had noOfSources

https://acoustid.org/track/635ea43a-491b-4967-98a6-2878b65f4d01

@lukz has this always been the case, or has this been newly added (because I thought they were only available when they had been matched to a MusicBrainz recording) ?

Either way if you use the api on this acoustID you get 5 recordings, i.e it shows each all five rather than showing three (two of them have two sources) which seems rather wasteful. Are there any plans to just return three records but with a numOfSources field so we can identify the most popular submission.

e.g

http://api.acoustid.org/v2/lookup?format=xml&client=apiKey&batch=1&trackid.0=635ea43a-491b-4967-98a6-2878b65f4d01&meta=recordings+releasegroups+compress+usermeta+sources+
