The approach there is very different, and personally I think it is not
the best route for the fill-column indication.

The main goal of Keith's feature is not the fill-column indication,
it's the "fake cursors", and the fill-column indicator is implemented
as one more "fake cursor" of sorts.  But if we want only the
fill-column indicator, implementing it as a cursor makes much less
sense, and is also significantly more complicated for no good reason.
Just look at the magnitude of the patch.  It's no coincidence that
this present implementation took so much less time and efforts than
the work on fake cursors.
