CONDSTORE represents a massive increase in IMAP synchronization 
efficiency (no need to fetch FLAGS 1:* for the entire folder), so if 
there are bugs in Thunderbird related to use of CONDSTORE, they should 
ideally be fixed rather than hacked around.

It looks like there is a lot of good data and analysis from WADA and 
other contributors on already, there just 
needs to be someone with time/interest.
