// shouldJSONEncodeSingleBareNode determines if nodes contain a single node that should not be
// wrapped and has a JSON file extension, which in turn means that the node should be JSON encoded.
// Note 1: this must be checked before any annotations to avoid losing information about the target
//         filename extension.
// Note 2: JSON encoding should only be used for single, unwrapped nodes because multiple unwrapped
//         nodes cannot be represented in JSON (no multi doc support). Furthermore, the typical use
//         cases for wrapping nodes would likely not include later writing the whole wrapper to a
//         .json file, i.e. there is no point risking any edge case information loss e.g. comments
//         disappearing, that could come from JSON encoding the whole wrapper just to ensure that
//         one (or all nodes) can be read as JSON.
