Yes.

*ANY* IMAP caching provides a performance boost.

The problem is that Horde_Cache is setup to handle discrete, singluar  
pieces of data.  IMAP caching instead requires multiple different  
pieces of data that are interconnected and need to be queried relative  
to each other.  Thus, the need for a more specific caching solution  
(we have to do all sorts of "tricks" to allow Horde_Cache to store the  
data).
