Wayland wants to avoid problems that X11, Windows, and MacOS have. It deliberately avoids some “features” that application developers expect. A lot of it relates to security and privacy.
An example is that a window does not know where it is positioned on your screen and it cannot choose where to place its windows. Personally, I love this behavior. It means I can open an open and it opens in a consistent location (for most Wayland compositors, that’s centered on the screen). But others don’t like that. They would like the app to control where it opens; for some apps (a niche nowadays) you may have an application window and multiple more supporting windows, but on Wayland, they would all just get opened on top of each other rather than being placed around the main window.
