I strongly disagree.  The gain is enormous - how much time would it
take to correct all these issues by hand?  (not mentioning that manual
corrections will break every time layout changes!)

what about beams?
{ g''16[ d'' a' e'] }
\addlyrics { la }

And while we're at it, what about rotated trillspans? ;)

LilyPond's greatest strength is beautiful /automated engraving/, even
for the people who don't have specialistic knowledge about engraving.
If we turn this feature off for some objects, it will mean that many
users will have sub-optimal scores.

I have one thought concerning computation time.
>From what i see, currently every stencil's skyline is created from 10
boxes.  That's a good amount for medium-sized slur, but it's not
necessary for a short (~5 ss long) tie, or a clef.  And it's
definitely overkill for an accidental; on the other hand, full-line
phrasing slur should have much more boxes.
Maybe it would be feasible to have varying amount of boxes for
different objects?  In it's simplest form, the number of boxes could
depend on object's width.
