I believe 63100 is the only one that is not in 7.1.2 today. My concerns with 7.1.2 are more with the following:

Have you done the work to isolate exactly what bugs are fixed in 7.1.1P5 but not 7.1.2? I could, but want to save wrist wear.
63100 isn't an issue for us. We have a bunch of IMAP users and a bunch of shared-folder users, but they are disjoint sets. I should perhaps be more concerned about what look like reports of potential XSS vulns, but since nobody is calling this a security update (of any criticality), I assume there's no proven exploit.
