I'm not sure if I agree. There are many frameworks in the devops space with each having their own DSLs that had various learning curves. For example, I see companies split between Puppet, Chef, Salt, Ansible, etc...

It sucks, don't get me wrong, that there one hasn't come away from the pack, but I don't think it's likely that any of these orchestration frameworks will go away. Each of them have a pretty dedicated following with lots of developers behind it.
