A common use case for me is to use a babel block to load a large dataset
into R.  I want this to be cached, in the sense that I want it not to be
run again (by e.g. C-c C-v C-b) unless the code changes.  But I also
don’t want to see its result in the (mini)buffer.  Is there a way to
accommodate this usage of the cache functionality?

In this case, the code block shouldn’t be marked :cache.  Unless the
desired (and odd, IMO) behavior is to have a datestamp that is only
updated when the user forcibly re-evaluates the block (with C-u C-c
C-c).

Also, with regard to:

The context surrounding this code binds cache-p; the lack of a hyphen
was just a typo in the patch.  I agree that cachep is more idiomatic (in
fact, that is what led to the typo), but I tried to make the smallest
possible patch to address my intention.
