I tend to side with Rune on this issue.  Dave's request would mean
that Lily would have to have the intelligence to detect what kind of
rhythmic patterns are in the piece, and that seems like a hairy issue.

 A semi manual solution is possible. if the user tells what kind of
notes should be regularly spaced.  I once implemented this, but I
threw it away together with the old spacing engine. The original
motivation was standchen.ly, a piece where there are running 8th notes
in the accompaniment.  Currently, their spacing gets botched every
time an 8th triplet is played against it.

With the feature you could specify regularSpacing = #(make-moment 1
8), and get regular 8th notes.  it was introduced in 1.5.2, and i'd be
very glad if someone would front-port it again (hint hint :-). It also
makes a ragtime piece that I tried to do with lily a lot easier to
read.
