That wouldn't work very well for the cases I was thinking about.
For example to get the same behavior that this patch puts in the range
window(of testgtk) would require an extra GtkAdjustment and 2 extra signal
handlers if we used only string mapping.

I can see how it would be very handy to be able to customize the text 
output to display the number as currency or just generally show the unit
of measurement.

I would say that both string and numerical mappings have their place.
Perhaps both should be provided.
