Not really, no.

Please suggest a better name.

The latter part is impossible. Most Lisp programmers don't understand
the fine details and issues with different measures of "window-width",
and it's infeasible to teach them all that complexity.

IMNSHO, that way lies madness. There are too many variations and too
many special cases.

Why does it make sense to complicate a single API instead of having N
simpler APIs that do the different jobs? What practical problem will
this solve?
