Love the thought you put into this, and as a project creator I do agree.
In this implementation I’ve tried showing as clear of a “full lane” for other creators to see the ability. Evolution closure set to zero is an infinite availability as well as there’s nothing stoping you from removing it all together!
For evolution closure currently my most aligned use case is “seasonal” / event unlocks that aren’t detrimental to the future progression if a large group of tokens did miss that stage.
Appreciate your thoughts Aaron!
