Personally I don't think the singer's status in either their own community or the 'folk' community makes any difference to whether we call them 'traditional singers' or not.

The great Arthur Howard, whose large repertoires are still in evidence in the communities where he sang in the Pennines to the west of Sheffield, had at least 4 distinct repertoires for different occasions, hunt suppers, folk scene, shepherds' meets, family dos, etc.

On the other hand another great singer from the same area who was much shyer and usually only sang for his family and collectors was Frank Hinchliffe. He had a relatively small repertoire.

I don't know of anyone who doesn't treat the memories of both singers with great affection and respect. In my opinion they are both equally 'traditional singers'.
