Speaking for myself, I'm all for fewer and simpler caches
along with instrumentation to back up the performance story.
(We got into this situation by having too much of the former

I don't think we have any illusions about content exposure but
whether there would be an issue with any particular approach is
beyond my pay scale.  Worth asking the leads *before* spending
time on development.
