Docs with detailed explanation on why this struct exist
SDFSpriteReference is exist for multi-version compatibility, in versions before 1.2.x it was holding more properties, and handled some custom serialization, but right now its just an wrapper around SDFSpriteMetadataAsset.
It will be kept in future versions as its useful to have some intermediate serialization layer, instead of plain object reference.
