ingy is batshit insane (and great fun to collaborate and/or drink with) but even he didn't expect text templated turing complete YAML to happen.
helm does still (last I checked) allow you to use your own transform script rather than the template engine so for private helm charts you can use https://yglu.io with data in environment variables to get less fragile templating if you can get away with doing it that way.
