it seem necessary to add support for other serializers ( json / yaml /
msgpack ) as well?
I don't think that adding support for configurable serialization is necessary for this project. Don't get me wrong, I think it'd be great if cache backends allowed for their serialization to be configured but I think it's out of scope for this project as no other core backends do so.
