The only reason we have games coming to Linux is Ubuntu. The only reason hardware manufacturers will be writing good drivers for Linux is Ubuntu. Not Wayland, Ubuntu. They do not care about Wayland, they already said they would not support it.
Why Ubuntu? Because Canonical is a reliable business partner and has a long term vision. Ubuntu has an excelent track record for delivering on time. Wayland just the opposite, it is more like Waitland.
You are not seriously suggesting we wait another few years for the people of Wayland to produce someting tangible but likely not what Ubuntu needs?
We have been waiting far to long. I am glad Canonical took matters in her own hands. Ubuntu will do it much quicker on her own and the end result will be better suited for what they want.
And who knows, maybe Ubuntu will do it in such a way that drivers are kept out of the display server, which would be a much better approach.
Open source is not monolithic development you want, it creates a free market. It offers choice. If Wayland wants to be viable it will have to proof herself by the product.
And it is wrong idea that more could be accomplished if all people work together on one project. We have seen that with Open Office. Since it was split, development goes much faster. Having all these in-fights between people with different ideas does not help progress.
