My point wasn't that YAML is an indefensible choice, but that embedding bash inside the YAML is at least to me not defensible. Making the `run` field take a string that's treated as a path to script within the repo would still give you all of the properties of "this config is data" without any of the nightmares that comes to multiple stacked layers of string interpolation in languages that are each already notorious for bugs from that sort of thing.
