Good, let's go for A !

Exactly!

I am going to follow the group preference on  whether or not to  explicitly
define the  subclasses of annotations ( i.e., define subclasses of
 dqv:UserQualityFeedback).

Taking a deeper look at [5] I realized they recommend to define a new
skos:ConceptScheme to include the motivations required by others
vocabulary. Now I understand your attempt to map dqv:qualityAssessment
into oa:motivation, which is pretty fine to me .. I'm sorry I did not
realize this at first ..

In view of that, instead of combining  the motivations from DQV and OA as I
had suggested in the issue description, we might think of defining a brand
new skos:ConceptScheme, and to map the new schema's concepts  into OA
motivations.

The new concept scheme  could have dqv:qualityAssessment  as top most skos
concept, and it could   narrow  dqv:qualityAssessment  with further DQV
 motivations   such as dqv:qualityFixing,  dqv:qualityQuestioning,
dqv:qualityClassifying.  These three new motivations can be  respectively
skos:broadMatch with  oa:editing, oa:questioning, oa:classifying.
Could this suit our goals?


 Cheers,
Riccardo
