There was a problem hiding this comment.
I think we also need to handle CelUint, bigint, Uint8Array, maybe also CelType and ReflectMessage: https://github.com/bufbuild/cel-es/tree/main/packages/cel#types
This could be a replacer: https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/JSON/stringify#the_replacer_parameter
YAML stringify supports it too.
Or it could be a function in @bufbuild/cel - but then we need to be very certain about it.
Or we could just have a comment here to clarify that this function doesn't handle all possible CEL values.
