^ global shortcuts was moved to portals (as it should be, portals are a much more sane way of handling this) but is in pretty much all compositors (except wlroots, but that's also being worked on and not in won'tfix)

I don't know what you're talking about with copy-paste, that has worked for a millenia

^ window positioning (although still being worked on, definitely not in the category of won'tfix)

https://gitlab.freedesktop.org/wayland/wayland-protocols/-/merge_requests/124

^ screencopy (screen recording)

Literally none of these things are as described won'tfix for security reasons. Also, wayland is a core set of protocols, you're meant to use the ext block for things that aren't essential for basic functioning (such as screenshotting), that doesn't mean they don't work or aren't implemented properly, they're done separately because they AREN'T core to functioning, there are certain compositors that don't want the ability to take screenshots, for example.

None of those were actually true, can you list an actual example?

Seems like FUD to me.
