These two properties definitely do not work anymore, and removing the
overrides in ly/ don't affect any of the examples in NR

This *seems* to be true, but since extra-spacing-width/height belong
to the item-interface, and extra-X/Y-extent belong to the
grob-interface, I'm a little skeptical that the two sets of properties
are related.

I think we should just remove the properties and add a convert-ly
rule, but I'm not sure how to write this sort of rule.  Not often are
grob properties *removed* from LilyPond without being replaced by
another property.  :-)
