What to do about CONDSTORE for GMail for TB 24?

If I'm understanding correctly, it'll be a loss in IMAP efficiency - 
there'll be more network activity with CONDSTORE disabled.

However, this amount of network activity will likely be equivalent to 
the amount used before GMail supported CONDSTORE.
