    Is their a way to set Electric Shift Lock Mode in the mode line?  I know
    about ZWEI:ELECTRIC-SHIFT-LOCK-MODE-IF-APPROPRIATE (or whatever), but I
    would like it to be on a per-file basis; If it is implemented, Update
    Mode Line doesn't do the right thing, and if it is not, how hard would
    it be to put in?  It seems inconsistent that Font Lock Mode is on a
    per-file basis while Shift Lock Mode isn't.

ZWEI:ELECTRIC-SHIFT-LOCK-MODE-IF-APPROPRIATE honors a Lowercase property
in the mode line.
