1) The list made by Jorge Carrion is pretty complete.

2) You don't write a window manager / a compositor just for some programs!

Each compositor is different, so you can't know by advance which 
features are available to your program when it runs, except the ones 
defined by the core protocol, and those that you check at runtime, but 
then you must know by advance which extension, and what they do exactly.

For example, KDE has implemented a lot of extension in KWin/Wayland so 
that features are equivalent with KWin/X11.

But you can't use these extensions if you don't use KDE libraries, and 
even if you use them without the KDE libraries, you are not supposed to 
write a program for each wayland compositor!

Technically, this is not really different with X11 extensions. It's just 
that the core protocol has missing features.

There is only one solution:

Someone enhances the Wayland protocol standard to get all the X11 
features (or most of them: the X11 system tray protocol is not needed).

For moving windows, it could be optional, or having an option at the 
window manager level ("allow windows to move themselves"), but the 
protocol must be present at the beginning.

But if there is some sort of Wayland decision group, it may take a lot 
of time to  be accepted, or be rejected. I have no idea.
