"While we can’t promise all problems will be completely gone"

They could promise to drop support for it once the wayland one reaches feature parity. If any "significant issues" remain, then it's simply not ready for release.

I hate this modern trend of releasing stuff before it is done. And in the commercial space we are now moving on to releasing stuff before they even get started on development. Selling promises. "Buy our shit now and we promise that next year it will be able to do X!"
