Hey Jindo
First of all, thank for for posting. There is a lot here that I personally agree with.
I agree with this, at least as an experiment, but you can see my support for that on another thread.
As for the adding features, I am all for adding features as well.
In fact, some of the features you suggested here are quite good in my personal opinion: https://gov.bancor.network/t/adding-features-to-the-bnt-token/
I do not agree with the ILP part, but I am in favor of the protocol bringing back a withdrawal fee when feasible.
One option, as you identified, would be to give to BNT holders. Another would be to build up some protocol owned ETH or direct to a future DAO treasury.
