Graham,
  From my point of view, Joe's last note on 1298 makes everything sufficiently 
clear to proceed :

minimum-Y-extent is still a valid property of every grob,
and VerticalAxisGroup does support the grob-interface (*1),
*but*
the Y-extent of VerticalAxisGroups is no longer used to determine the spacing 
of staves, so this particular use of minimum-Y-extent should be removed or 
replaced from manual/web examples.

The convert-ly pattern that flags this change should be restricted to something like 
"VerticalAxisGroup\s*#\'minimum-Y-extent".  That would be a different issue, 
and I am about to report it in combination with a closely-related missing converty-ly 
rule.

(*1) One might wonder why VerticalAxisGroup supports the grob-interface, being 
that it is not a graphical object, but that question seems outside the scope of 
this issue.
