Perhaps a more limited YAML library like Poyo would address some of the concerns we have about using PyYAML.

Poyo in particular may be too limited, but I wonder how much it would sway people if we used YAML but not PyYAML.

Anyway, here are some relevant snippets from Poyo’s README:

Please note that Poyo supports only a chosen subset of the YAML format.
It can only read but not write and is not compatible with JSON.

Poyo is 100% Python and does not require any additional libs.
