They should be totally added for wolfmarks and crystal trophies some day?... Even if it's a high amount, since these currencies need sinks to encourage people to PVP.
Personally as somebody who earned them all in every pass as they happened, I don't want to take any claim of deserving exclusivity in perpetuity, since gaining them was merely a grind and not skill. It's not like the Feast or Ranked CC rewards where I don't mind since the players (hopefully) deserve to keep that exclusivity. besides which; It would be nice to be able to obtain them on any potential future alts, especially the emotes and framer kit stuff. (also, i threw out a helmet by accident, which means I have glamour dresser slots I could be saving with the new set system... which I can't since these rewards can't even be reclaimed. :< )
