Can x11 watcher be used until proper wayland watcher exists? Wayland seems to emulate primary/clipboard reasonably well for the legacy X11 apps.

Yup, x11 should work just fine. The main reason to add a native Wayland implementation is performance.

Work remaining:

• Support claiming selection ownership
• Automatically trigger a paste

Seems like I should be able to create a virtual keyboard from https://wayland.app/protocols/virtual-keyboard-unstable-v1 and get the keymap from https://smithay.github.io/wayland-rs/wayland_client/protocol/wl_keyboard/enum.Event.html.
Though actually I probably need to research https://wayland.app/protocols/text-input-unstable-v3 because that seems like the correct way to insert text. Hmmm, but I don't think I could insert stuff like images as that requires the application to run its code?
