Yes, we are definitely interested.

Yes, these changes can be made piecemeal.  We already did similar
changes in the past, like converting the x_*, w32_*, and ns_*
functions into platform-independent gui_* functions.  The trick is to
make this safely, because there's a possibility of never reaching the
end goal, due to Life(TM) or whatever, and so too deep changes that
increase complexity but are not taken to their projected goal are a
burden we should avoid.  Small changes, which make it easier to
parameterize the implicit window-system dependencies and make them
explicit, and thus move us towards the goal, without introducing
unneeded complexities, is the way to go.
