This is interesting, the problems you're describing are exactly the ones I want to take care of implementing myself. I don't want built-in user management - the way I want to handle users will more than likely vary between projects. I'd rather worry about the implementation of the app than stitching together frameworks to start out. I can go from `rails new appname` to having a working blog in about 15 minutes, which is an awesome way to start a project. Get it working, then worry about whether you want Turbolinks or not. Because starting out, Turbolinks and jQuery are Good Enough™ to get most projects going.
