Well, given a "well-behaved" family of quantum groups, which are deformations of the same group, is it "natural" to define this family as a homotopy type? Is HoTT, in some way, a natural setting to work with quantum groups because types and homotopy types are identified?

My understanding of quantum groups is that they are supposed to be groups with "noncommutative underlying spaces", and the homotopy types of HoTT are all "commutative" in this sense.
