People have to remember that the sub they pay is not going into FF 14. All the sub money and all the money you give them through retainers, name changes etc. and buying the expansions gets put into Square Enix itself and then the FF 14 has to go to the upper management and ask for small amount of moneys to develop the game further. Every time they do that they have to explain why they want to do it and how much money it might make. The only money that the FF 14 can keep is the money from the Mogstore Items.

And as sad as it is, they most likely can not really motivate upper management to give them money to develop weapon glams as that is not a feature they cann sell to them as something that draws in new players and more money.
