Well, that sounds like Google haha. I’d drop it just for that reason alone, to be honest.

> The real issue is that Google should not be the arbiter of what apps are allowed that kind of access, and they certainly shouldn't be making small developers jump through the expensive, ineffective CASA hoop to get it.

Absolutely. In case of whole Drive access, I think a big scary warning should suffice here: the user should understand what they get into, but still be able to continue if they want. Perhaps the warning can be made less scary if the app passes an audit (something more suitable than CASA, of course).
