Everyone asking for more summons rather than more skills
Perhaps this is what they had in mind? The devs may have realised that they can't add pets at the rate that new primals come out (resources, balance etc.), so what they decided instead was add one new pet every now and again (4.0), from there the egi glamour system allows them to add the new skins for the primals that people want to see. The result being that we get more pets, and get the egis we want to see in the fastest possible way.
