I'm not sure who you are being sarcastic about in the end, but yes, Wayland is indeed clean and simple enough to not particularly discourage alternative implementations.
For example, it's vitally important that wayland resists adding features like title bars, window icons, resize handles, desktop icons, or mouse cursors. These frivolous features have no place in a serious desktop environment! They are only bloat!
"tantrums" is when you expect windows to be delineated with borders apparently. You got the Wayland attitude down pat: are we the problem? No, it's the users who are wrong!
Indeed, we agree.
We just need to do the hardest part: keep it clean and simple to not particularly discourage alternative implementations... on the long run.
