Open source doesn't really work like that, there is no top-down decision maker setting priorities for what should be done in any given distribution. Usually what happens is you wait until it becomes enough of a problem that some distribution fixes it, but this one is low priority given that distributions would probably prefer to focus on native Wayland ports for the software they have control over that is packaged in their distribution. And for the external software they don't have control over, it's much harder to find people to work on those.
