I would argue that the layout engine should work based on the
em-square of the font, which would result in consistent and
predictable spacing. The way it is in 2.13.24 though is essentially
unpredictable since you can’t know what the output is unless you know
in advance what the lyrics text will be.

+1, though the workaround by specifying VerticalAxisGroup 'inter-loose-line-spacing 'minimum-distance is easy and straightforward once you know it. There also was a discussion about the optimal value on the LilyPond-devel mailing list a few months ago: <http://old.nabble.com/%28bug-%29-irregular-lyrics-distance-in-2.13.10-td27145106.html>. Not sure though whether Joe pushed the value of 3.2 we seemed to agree on. Joe?
Sorry, I had forgotten about this. Actually, the nabble page doesn't seem to show the whole thread, in which preferences ranged from 2.5 to 3.2. In order to head off a potential bikeshedding, I'm just going to push 2.8 and be done with it.
Cheers,
Joe
