For people who absolutely have to have X11 this looks like a better plan than XLibre.
Until Wayland actually has an accesibility story, X is really the only choice. Don't think most grassroots projects will have that.
Long term if x11 starts having issues then probably https://gitlab.freedesktop.org/wayback/wayback will be it
I’m not sure this satisfies X11 needs without remote display capability.
The people who absolutely have to have X11 like myself usually have reasons. It sounds like currently a lot of those reasons for using X11 would prevent using this X server. Like reliable non-fragmented and widely supported screenreader protocol. Or the ability to do keyboard and mouse sharing.
>Applications will be isolated from each other by default and can only interact with other applications either through a GUI prompt asking for permission, such as with screen recorders, where it will only be allowed to record the window specified or by explicitly giving the application permission before launched (such as a window manager or external compositor).
People who want to use X11 are likely to be the same people using older software and hardware, which this doesn't support.
It depends on whether their reasons for "absolutely having to have X11" hinge on actual compatibility with e.g. old binaries or wanting full remoting without streaming pixels.
This project would satisfy people who really actually want Wayland, but were upset by transitional pains or interactions they had around it and want to stick with X11 just-cause while getting some similar benefits. This arguably does describe some people but not sure it's a whole lot in the long run.
But who knows, maybe this could also make an easier to maintain XWayland some day, or a nice basis for implementing more esoteric X11 bits down the road vs. the older Xorg codebase.
