Poyo in particular may betoolimited, but I wonder how much it would sway people if we used YAML but not PyYAML.
If we found a reasonable library for parsing YAML it might be a more reasonable alternative. Though I think we really need something that supports most if not all of YAML otherwise I think it starts to get confusing because you have to figure out what the specific subset of YAML that the library that whatever packaging tool you’re using supports.
