Hmm.... SMN has 3 pets, SCH has 2 'pets'. SMN feels hard done by because they won't have more than 3 pets, which apparently required an apology and developer time to develop an entirely new Ei glamour system; but Sch still only has two 'pets'. SMN get all high and mighty saying that they deserve this and SCH does not, and still SCH has only 2 fairies that they can bring forth.
So you already have more flexibility and variety than SCH, but because SE decided they would not extend that, you get an apology in the form of an exclusive glamour system? And you wonder why SCHs are questioning this?
