This is true with more "modern" setups. I tried rustdesk with Wayland. It somewhat works, but you have to be present at the "remote" PC to click a button allowing the sharing.

I periodically retry Wayland, and it does seem to be improving, albeit slowly. There are a few significant things that just aren't there, but mostly it feels like death by a thousand paper-cuts. I can't dock toolbars; I can't use xdotools; screenshares are flaky; I can't click and drag to upload to browsers.

I could live with Wayland, but the experience is still superior (for my use-cases) with X11.
