Yes it is and if you dont see the benefits of knowing the roles of your 
machine or containers and using roles in your infrastructure I cannot 
help you.

Making statement like this just because they might not be useful to your 
usecase scenario or workflow is simply silly.

My best advice to you if this would get implement is simply dont use roles.
