Will Wayland also ship with broken keyboard layout switching?

Hi,
sorry if it's not the right place to ask.
Afaik Wayland uses a lot of X11 code for keyboard keys mapping/management.
In 2008 something broke in the X11 input stack that doesn't allow any longer to
switch between different keyboard layouts (languages) using both alt keys. It was
very handy btw. Since then I'm using the usual (but less handy) "Alt+Shift" keyboard
combination.
Can anyone please check if Wayland/Weston has this issue to? i.e. can you switch
between different languages with "both Alt keys"?

Here's a few bug reports, some people tracked it down to the (new) XKM
file format but nonetheless hasn't been fixed:
