Have an example where pure-from-neighbor would do better than
axis-group-interface:height ?

You might have understood me backwards.  An overestimation in tentative
(vertical) space between Staves/Lyrics/Dynamics will let the spacing
spanner do sometimes a /tighter/ horizontal spacing.

The overestimated tentative vertical space is forgotten when the
real vertical spacing is done.

I didn't see, and don't see any risk of, loose spacing from this patch.

I expect that occasionally, this patch will let a collision with a span
bar leak through, but it would be something crazy like an \espressivo atop
a \downbow on a note connected to a cross-staff slur.  The \espressivo
isn't pure-relevant because of the cross-staff poisoning.
