Worth keeping or selling items with Guild Augment slots?

[Pointyears]

So apparently they ditched Guild augment slots in Update 17 but they still exist in game (as do the vendors in House K).

I'm guessing if anyone ever sold these items for crafting they might be really expensive? or do you think no?

Toying with the idea of at least selling tiny guild items and keeping the small or medium ones depending on guild size to use it.

Thanks
