I know I've given my three cents about pure from neighbors, but I believe that 
LilyPond functions best when she thinks like a human engraver, and I am 
convinced that this is the thinking that runs through the head of engravers 
when they do their thing.  They have a graphical object and they know that they 
don't want collisions with the object, but there is also "air space" above and 
below (just go with me on the below...it kinda ruins the air space analogy, but 
you get the idea) the object that they don't want to be flown over/under.  This 
space must correspond to the heights of the neighbors on the staff but not in 
other contexts (like Lyrics).

I see that these measures have gotten shorter, but where is the problem?  What 
is the standard against which this regtest is being compared?  The texidoc 
string doesn't make any mention of the length of the measures as an indicator 
of correctness.  Do you have the impression that multi-measure-rest-length is 
detrimentally affected in lines of real music?
