I'm confused.  A change in display would indeed be impossible.

Turning display into a shorthand property that still accepts all the
single-token values is completely backwards-compatible.

Take a look at what I've actually done, and how I've split things up.
I think it's much closer to what you are thinking than you realize.

That's very nearly what I've specced.  There is a single 'table' value
for display-inside (the "flow" property).  All the other table values
are display-outside values, which just describe how they interact
inside of a table flow.

(There is also a 'table-inside' value for display-inside, but it's
just to make everything work a little more smoothly.  It doesn't
actually *do* anything.)
