wayland initially was infested by the type of developers
Wayland was founded by the X developers who wanted to call it X12 but realized that people would freak the hell out if they fixed it the way that it needed fixing, based on their experience with X11.
Did you know that X11 has no security and that any stupid app running at the same time as your password manager can steal your keystrokes? Wayland fixes that, among other improvements to the 1980's architecture of X11.
Besides that, the baroque layering that means that you don't get good performance on modern hardware (because some breakage is considered unconscionable by the software conservatives). Those people can stay on X11 until they're old and creaky or their identity is stolen and they're too broke to own a computer.
Their kind of thinking is why traditional Linux DE's are stagnant and just adding circus tricks while ChromeOS and Android are the most successful linux distros.
Thank you, FESCO.
