despite the readability of the yaml syntax, for me the big disadvantage is the inability to use meta / type info.

for a straightforward collection of strings: probably good enough, for anything else xml is more likely to cover the usecase better

YAML has really good typing support with type annotations being a first class citizen. But you’re dependent on the hosting software (adding or understanding) the types.

For example

    start: !date 2020-09-12

could actually map to a native date object.
