Price feed only takes place on the top 20 witnesses... so its not useful, just an exercise, same with the APR stance.
Growing as a backup witness should be about learning... it should bring pressure over time, and should bring blockers eventually (top 20) about how you bring security to the chain in terms of production.
I have the luck of being super stable... but someone else might not, and we still (need to) defend the chain stability.
Being decentralised is way harder than people think... even I don't really grasp all the outcomes at the age I am living my life.
Yes, we want everyone to discover that, but it's not easy to teach. And not everyone wants that... even if I keep going...
Reality... is hard sometimes.
