Thanks!
Your question is quite vague, but I'll try to reply best I can.
Sufficient flexibility in what sense ? We can definitely adapt any token economy, and some of the ideas behind smts go that way, they would allow you to test a lot of token economic models really easily.
Right now is definitely a way where we are more open to ideas than ever before, if you have ideas don't hesitate to write a post with lots of details in it to expose your ideas and start the discussion :)
