Indeed. Sorry I missed that.

But I'd say it is slightly awkward to add "x-" for all these (for me,
"x-" means more like "this is not stable and experimental, use it
carefully", while this does not suite for this series). Maybe I can
just remove this sentence in commit log (I think I am just a little
bit frightened by the compatibility problems)...

Thanks,
