Looking at your description, maybe I'll go back on what I said earlier
properties first-system-spacing and first-system-title-spacing that can
control stretchable space and minimum distance between the top margin
and the first music system or title. They can also specify padding
between the header and the first music system/title.

It seems like that would obsolete head-separation, right? So I'll
probably just remove it.
