I can't say how much time it is worth to you, sorry. What I can say is that screen sharing works fine under Wayland and Gnome for me (AMD hardware all the way), so I'm inclined to say that Wayland is not the showstopper here.
anyway, if one of the majors tiling wm managers struggling to share specific window it looks like it could be more edge cases like that. Probably, I can deal with those things but I fully understand struggle of this article author so just wanna upgrade to it when possibility of struggle will be minimal for me.
