Has there been more clarity on whether crypto POS staking and delegation income triggers self employment tax?

A couple of years ago, there was a debate between professionals who were recommending paying self employment tax because this is how POW miners are treated and another camp who recommended treating it as Other income and paying self employment tax isn't necessary unless you actually have a real business around staking (i.e. running many nodes, staking as a service business, etc) which makes sense since the hobby staker often doesn't even run their own node especially if they're just delegating. There is no office space, business costs, hardware to set up like with POW miners. 
I was just wondering if there has been a more clarification around this.
