But at the same time there is little chance say Puppet, Ansible, Salt, Chef would just write their newer/better system but will try to emulate some other existing language/DSL. For example do you see Chef taking off and becoming popular if it just implemented Puppet's language. Or would Salt have any appeal if it just had the Ruby syntax like Chef does? It just won't happen easily. One reason is because the API surface and the DSL is so varied that chances are there were significant design mistakes made in a previous version. And one of the reason people want the new shiny is that it fixes some of those fundamental design issues. Copying and emulating an existing thing, means sticking with broken fundamental design decisions. The irony is of course the new shiny also has it own fundamental design flaws and so now there will be a new group of people implementing the newer and shinier thing.
