Hmm.

Strange.  I have at least one CC who swears that he's seen/used that
link.  No matter.  I can certainly see the desire to reduce system load.
 Those spreadsheets are a beast.  But we've seen non-reproducible
instances where for some reason the caches seemed to not be cleared,
even after several hours.  I think it might be nice to give CC's the
option, especially say at the end of the semester, with some kind of
appropriate warning.  I'll submit an enhancement request.
