Satisfied doesnt come into it. Im realistic about the level and type of changes that the devs would consider for the game. I have a basic understanding of the framework of the item and crafting systems they built. And i understand that your idea is not compatible with what they have. So to add it they would either have to make 2 brand new systems and then maintain all 4 of them going forward(so that old items/crafting continued to function while your new ones would work going forward) or they would have to throw out the baby and bathwater while building your 2 new systems(with this version also requiring reworking all existing items to fit the new system). You seem to underestimate the amount of work this would be, while you seem to overestimate how much it would "improve" the game. Most of the players would either never notice or would see the change as a negative.

Going back to glams, i am unaware of any items you cant glam. There are some items you cant use AS a glam, and there are rules(cant glam a higher level item onto a lower one for instance). But you should always be able to apply a glam to your gear(once it is unlocked of course). And a master already makes a better sword then a beginner. A beginner uses simple materials and nothing else. A master uses advanced materials and advanced techniques(applying reisui/alkahest for instance). Anything beyond that is a balancing issue.
