I've thought that there still were no consensus on x-foo prefix,
not to mention that x- might be legitimate prefix for some properties.

Maybe we should add a flag to property like INTERNAL_PROPERTY
and then set it explicitly on for internal stuff.

That way we could cleanly exclude internal properties from
 -device foo,help and make sure that user won't set them from CLI.
I'd even volunteer to add this API to Object
