Even if you think that it entails more stuff, like knowledge about AWS, rackspace APIs, provisioning tools and whatnot, it's not enough. Mostly because in any medium to large company they build tools and processes on top of them. Have fun learning all of that, while you only need to commit your code.
Plus, since I've been for many years a sys admin guy that turned into a developer, I can tell you that there are different skillsets involved, albeit with some overlapping ones.
That's where the devops come in.
