All that for _one_ feature which works out-of-the-box with Xorg, and which Wayland removed for security reasons. From what I've seen, sharing the screen is another common feature which was broken with Wayland and is still painful.
I don't think Wayland's security model is very relevant to me since I have faith in Debian for filtering out rogue applications. So I have to reason to drop my smooth UX for a world of "not too bad" workarounds.
What are you talking about? It's very convenient when I watch video while I do some work or entertaining thing on other web page or app. It's fine if you don't want to use it but many people do.
