I think there are two cases. One is where the titles/labels are part of
the field metadata. Another is where the allowed_values and their
titles (and even descriptions, etc) come from some content source. I imagine
you could solve the latter by using a custom widget responsible for
displaying the labels, though in some cases there may be some trouble
hooking up the labels to the values. Conceivably a third case is that
this is a responsibility solely of the widget, though ordinary 
field titles aren't and these titles would seem to describe the content
just as much as they do.

I don't understand what you mean by it only affecting the cache selection
views for cachable objects at this point. Is this it the only code
that uses selection lists right now?
