Huh.  Sorry that I missed the weekend discussion; in general I support 
these names.
I'm not quite sure if they will be clearer to the "everyday user" who 
mainly thinks in terms of titles and scores, headers and footers, 
though, and probably won't have a bunch of settings for all of these, 
but rather uses the default for everything but what used to be 
'after-title-spacing. [1]
But since the new names are consistent and I definitely lack to come up 
with something more clever, I'm satisfied.  (At least until GLISS, that is.)

[1] I tried to figure out what's the buzz with scoreTitleMarkups and 
bookTitleMarkups.  From a user's POV, both of them are 
top-level-markups, right?  Is there anything different because one 
belongs to the score and the other to the book (aka "real" top-level)?
I think after-title and between-title are the perfect identifiers for 
the spacing between those, but the whole naming system gets messed up if 
you include custom markups.  /Perhaps/ I'd like aliases, but I don't 
want to think about this until GLISS.  And, essentially, aliases are 
ugly anyway, so encapsulating headers in a separate category (score - 
markup - headerMarkup?) may be better, or...  Not something to discuss now.

By the way, right now it isn't possible to change spacing /in between/ 
of a book environment, is it?  It's reasonable to think that the very 
main header (and the very first music line) will need a different 
spacing than all other markup-system-pairs, even if a scoreTitleMarkup 
is absent.
So it'd be cool to allow changing the spacing variables inside the book 
block, or have some LaTeX-\vfill-like command with the four spacing 
variables as arguments:  \vspace #'((spacing . 5) (stretchability . 
20)), ... you get the point.  But again, this looks like a major (read: 
postponed) change is necessary.
