Well, "centre-of-staff" does not really have a dependable definition for  
irregular stafflines, does it?  "normal staff extended temporarily" would  
_definitely_ benefit from using 0 as a default as then the time signature  
would not move around when the staff is being extended.

Staff_symbol::line_positions calculates (-3 -1 1 3) for a 4-line staff and  
(-5 -3 -1 1 3 5) for a 6-line staff unless explicit line positions are  
given.

plainchant does not take time signatures as far as I know.  For (-4 0 4),  
the 0 position does not seem unreasonable for the time signature.

I don't doubt your experience as a musician.  I just don't follow the  
programmatic conclusions you draw from it.

Also as a programmer and user interface designer: if it is not possible to  
pick the correct solution 100% of the time, the next best thing is to pick  
a _predictable_ solution that can easily be adjusted.  An override on  
Staff.TimeSignature #'Y-offset will do just that.
