You could probably use 'container commands' to start/stop worker processes after each deployment. I'm only reading the Elastic Beanstalk docs for the first time, so I haven't tried it myself - but it looks like it could be the right solution:

True, but it would be nice to have separate instances for workers vs app servers.

Oh absolutely. As you said, procfile (or similar) support would be amazing.
