Cyicism aside, the don't have to allow every piece of glamour right away. They could treat it like the armoire, where they expand what can be stored, as they can afford the data increase. At the very least, they should allow some type of alternate glamour storage the more difficult pieces of gear (tome/token gear, CT gear, VA gear, etc), especially after it becomes completely obsolete.

There's also a good majority of existing already data that could be reused to populate the glamour log. Every glamour option doesn't need to be unlocked the same way. Items stored in the armoire, crafting log completion, achievement data and quest data can all be reused to unlock certain glamour options.
