These are good points. I believe that if you have a few critical apps with a reasonable load and need to scale beanstalk is the way to go. Otherwise you're just getting into managing your own PaaS infrastructure for what? For nothing.
If you've got a bunch of small one-off services you deploy all the time and want a bit better density and an nicer deploy story, then sure do up a small CoreOS or ECS cluster. Or maybe you're very large and your resource requirements so high that having tons of spare capacity around to run up containers in makes sense.
