Version a) becomes quite more efficient once you change more than a
single setting in the same context definition since it only copies the
Score definition once per context definition while b) copies it once per
music expression.

Also a) changes a single context definition while b) changes all context
definitions that have an alias of "Score" as well (for "Score" that's
rather unlikely, but for "Staff" there are a lot more candidates).

No.

Depends on the context definitions in ly/engraver-init.ly.  Does not
appear like ClefModifier is touched there (after initializing it in
Global from all-grob-descriptions).

So any such situation will be created by yourself.
