Can future relic weapons have special abilities?

[aurace1095]

I frequently see the argument that any special stats would immediately become mandatory, and people would be discriminated for not having them. Yet, there are plenty of opportunities for this to happen already in the game, and it doesn't. Do you ever see a farm party in PF that requires A4S weapons, or even Thordan EX weapons? Drops from those two events give a substantial stat increase, and excluding people without them would speed up your runs. But it doesn't happen. Why would adding new and interesting stats (to either all gear or only rare / hard to get gear) suddenly cause this to start happening?
