SE is likely shying away from allowing crafter/gatherer gear from being worn by DoM/DoW because of the big stink it caused with DoM/DoW spiritbonding in high-level instances. So, I don't think it's likely we'll be going back to that.
That said, for GLAMOUR, I totally agree that SE should do away with the class restriction nonsense. There was SOME justification in it in the beginning, in that they wanted tank classes to look armored and mage classes to look clothy, but all that went right out the window as soon tanks started glamouring bikinis and such.
Plus, it would save the developers from having to waste time creating recipes like Uraeus Coat, whose sole purpose is to be a glamour item that looks like Kirimu Coat.
