I'd like mining pools to offer sale of coinbase bitcoins for people who truly value their privacy. I would buy a 12.5 BTC coinbase transaction for maybe up to 13 BTC. That makes the pool's effective block reward 13 rather than 12.5 BTC. More reward means more users so the pool would get bigger, mine blocks more frequently, more profit from coinbase sales. I honestly don't see a downside.

NB. When I say 'coinbase' I mean coin generation from mining reward. Not the company. (I hate that they deliberately chose a name to confuse new users)
