I think for a change like this we should start small. There are two things at play for me:
- The perception of fairness and how users may react to the change (which I outlined here);
- It will be psychologically easier to increase this value than to lower it in the future - the change effectively adds a certain amount of power to MNDE, and people react better when you increase their power than when you reduce it;
I’m comfortable with 10%, but around the 15%-20% range it starts feeling less like something we’re experimenting with and more like a change that will be harder to roll back if we realize it had some side effects we did not like.
(Likely because I currently wouldn’t want more than half the stake controlled in this way, and 20% it would be well into that percentage)
