Yes.  I'm not trying to hide staffs.  If you're saying the solution is to
have however many multiple staffs that may only occur for a few measures
entered into a part of multiple hundreds of single staff notes, that's not
really a solution.  

If you compiled the above example and noticed that what I typed in is
basically this:
\version "2.18.2"
\score { << \new Staff { relative c' { <c g'>1 c <c g'> c } }
\new Staff { relative c' { <b f'>1 b <b f'> b } } >> }

but what comes out is this:
\version "2.18.2"
\score { << \new Staff { relative c' { <c g'> c <c b> c } } 
\new Staff { relative c' { <b g'> b <f' g> b, } } >> }

The notes are correct, the layout is wrong.

There's something wrong in the way that staffs are grouped if multiple
staffs are called later in a part.  

If you take the breaks out of the example above, the second new staff is
dangling below the staffs.  Which says that "\new Staff" isn't a singular
(atomic) call.  Maybe it's a problem with layout?  Perhaps \new Staff should
have some function where you name it, e.g. "\new Staff = part1staff1" and
"\new Staff = part1staff2" which would which would group them correctly.

I don't report to the bug list without reason (read big annoyance).
