I used bitcoin quite heavily in 2016 through the 'shift' card that coinbase offers, and I think I'm going to hold off on further use in general until tax stuff is more clear / straightforward - I've made an effort to pay the bitcoin taxes correctly in previous years, but not personally being an accountant, had to hire one to check all the stuff (I'm not super rich, so this is a little bit annoying). The point of this comment is that I think it is a good thing coinbase is trying to standardize some reporting method - I also agree with the '1099 for each cup of coffee bought with bitcoin' seems a little bit much...
