Who and why really need 3.11 applications for today? In my opinion, this is not
a good reason not to add Wayland support for Wine. Moreover, Wayland support
for Wine was announced by Alexandre Julliard at WineConf 2016, but for reasons
unknown to us, no work on its implementation is still visible. Well, then when
will the native Wayland support for Wine be implemented?
Thank you.
