If you would like some feedback from an user, I think that Wayland should be the default now. Yes, GNOME still does crash, yes there is no viable screen-sharing, etc.
But, the user still has a choice on the login screen, and this is already well documented on Buster's release notes page. Wayland has to become default because it need wider user-base. Remember that Debian developers can fix any critical bugs via future Buster point releases. Leave the choice to the user, and stick to upstream's defaults. Anyone who installs GNOME on Debian should know about Wayland and be informed about it's limitations. So, let's try to fix those limitations. Sincerely, a Debian GNOME user
