Yes, this would work, but there should be a markup command for the stuff
behind \markup.  Basically the idea was to give a bit more flexibility
about where to draw the borders for making a nice interface, and also to
make it easier to substitute one's own stencils when the defaults are
not sufficient for one's needs.
