You're essentially encouraging people to give up and leave it broken.

Sure, a lot of code changes need to happen, but they only need to happen once. There's no real reason to discourage people from stepping closer to the end goal.

Like... I don't exactly want to discourage people. As a person using a11y tools that don't yet exist on Wayland, I would kinda like to be able to migrate over. But it remains true that Wayland is set up in such a way that it's inherently a longer uphill struggle, and always will be. If tomorrow someone created a new X11 window manager, I could switch and my tools would still work. If tomorrow someone created a new Wayland compositor, I almost certainly couldn't use it, because they'd need to implement everything over again. They can do that, obviously, but the startup effort will always be higher.
