Comment #11 on issue 1298 by joeneeman: minimum-Y-extent might be obsolete?
http://code.google.com/p/lilypond/issues/detail?id=1298

The Y-extent of a staff no longer affects the vertical spacing of staves.  
Therefore minimum-Y-extent (which affects Y-extent) no longer affects the  
vertical spacing of staves. I think that this use of minimum-Y-extent was  
by far the most common (certainly it is the case for all of the examples in  
comment #1).

Of course, minimum-Y-extent has an effect for _some_ grobs, since the  
positioning of many grobs depends on their Y-extent. So no, it is not  
obsolete, but it will probably be less used in the future.
