AFAIK, RFC 3851 (S/MIME version 3.1) is fully functional. The new
features of RFC 5757 (S/MIME version 3.2) are not supported.

I would consider it a very bad decision to remove support for S/MIME. I
believe that S/MIME is more widely adopted than OpenPGP. Outlook, Apple
Mail and many more mail clients support S/MIME, and I fear we'd loose
*many* users by removing S/MIME from Thunderbird.
