All this reconfiguring of aircraft costs money, seems wasteful (old seats are presumably discarded), and adding seats contradicts the idea of capacity discipline.
It similarly seems like an expensive waste to rebrand aircraft and service as D1, C+, etc. It confuses both the customers and the employees (FAs, phone agents, etc.). In the D1 case, it causes a risk that international business class tickets won't be reimbursed because someone will think that DeltaOne means FC.
