To be removed, most is just a plain crap.
Even the parts that were related to WinOS2,
were a total crap, see this for instance:

It still isn't in most cases, yes.

The trick is to bypass the windows
ring0 startup code and run its kernel
directly. It requires only a little of
ring0 - LDT read/write access. Virtualization
of LDT appeared to be possible. Minimal
VxD code was stolen from Wine.

Or you can try to do that yourself, which
would be a bit faster than waiting:)

I agree that the screenshot section would be
nice to have, but as for Win31 - there is
nothing new as you could use WinOS2 patch
since dosemu-1.2.0. And running the unmodified
one gives you no advantages. And you still
need the mouse driver from WinOS2 if you
want the mouse in Win to work under xdosemu.
So it won't be any better than here:

Mainly I view that as a first significant
move towards win95 support, but nothing more.
