TeX's algorithm is that the baselines of successive lines are placed
\baselineskip apart, unless that makes the depth of the previous line
and the height of the current come closer than \lineskiplimit, in which
case the separation is chosen as \lineskip.
That's sensible, even though Lilypond could likely employ skylines for a
better "closer than" criterion.

No, that is not an option. If you have lines without descenders and
ascents, like
\score {
<<
\new Voice = zap { \relative c' { c4 c c c c c2. } }
\lyricsto zap \lyrics { a mouse races worms across manure }
\lyricsto zap \lyrics { a mouse races worms across manure }
>>
}
the result becomes utterly illegible.

Line spacing is necessary for readability. You can't just run things
into one solid grey mess.
