I'm definitedly not an X apologist but what you wrote is *very* inacurate!

False: when your toolkit drops support for X to become Wayland only (let's be realistic: backward compability support isn't good in the Linux desktop world), then "Wayland can make things worse for you".
It won't be Wayland devs's fault, it'll be the toolkit devs fault but if there are users for which "Wayland experience" is worse than "X experience" (I hope that there won't be, but I'm not sure that this won't be the case) then **they will still have problems**..

Only in the sense that Wayland is X's successor but X is a model where programs send drawings commands to a display server, Wayland is a model where programs sends whole buffers to a display server, that is a significant difference: drawing commands can include 'send a whole buffer' but not the other way round.
