A "sensible protocol" would be a flat frame buffer with
a single color depth.  Unfortunately, the vast majority of
today's customers for add-in video cards want the fastest,
most featureful 3D rendering engines.  Presumably many of
the details of the 2D interface are dictated by the needs
of the 3D design, including the bus cache.  Of course, the
"standard" VGA/SVGA modes that evolved step by step from
the original IBM VGA over the years must still be supported
for such things as Windows "Safe Mode".

The mouse was never (on the PC platform) closely coupled
with the display.  Typical PCs do not "need" a mouse, but
it is more tedious to navigate in Windows via the keyboard.

It really doesn't seem that such a design would be competitive
today.

I think you left out a "b".
