I'd be shocked if anyone other than Dave Cridland (the author of the 
Polymer client) is using CONDSTORE support in Cyrus 2.3.  Not only do 
you have to have a CONDSTORE-capable client, you would have to have 
enabled CONDSTORE support on one or more mailboxes by setting the 
correct mailbox annotation.  Since very few, if any, clients support 
mailbox annotations (ANNOTATEMORE extension), the user would have to 
very good knowledge of the IMAP protocol or access to cyradm to enable 
CONDSTORE.

So, a 2.3.7 release without the CONDSTORE replication fixes would 
essentially create a replica with CONDSTORE disabled on every mailbox, 
which is probably going to be an accurate image of the master in 
virtually every installation in the wild.
