Somewhat. At least it is probably at a technically stable point where 
software developers are no longer chasing a moving target. IETF "Last 
Call" isn't entirely a formality, but it is a strong sign that nothing 
major is going to change before the RFCs get published in final form. I 
strongly hope that it gets implemented more widely in servers and 
clients. I'm not entirely convinced that JMAP is a compelling advance 
for anyone but coders. On the other hand, the tendency of coders to burn 
themselves out on the baroque edge and corner cases created by IMAP and 
its many implementation variants trying to satisfy users conditioned to 
expect 'enterprise-like' functionality in Internet email may be a good 
enough excuse for simplifying email developers' work. If I had a 
potentially usable JMAP-capable client, I'd probably stand up the JMAP 
Proxy in front of my own servers to give it a try.

With that said, I HOPE Benny resists the urge to implement JMAP in 
MailMate unless and until he has enough paying customers to delegate 
work to another developer and has a more manageable list of pending bugs 
and planned features. Maybe after 1.x is closed out and 2.0 is the real 
release?

[Full disclosure: many years ago I had some minor and entirely friendly 
professional interactions with Bron Gondwana, now CEO of FastMail and 
JMAP evangelist,  making me a bit less cynical than is my norm regarding 
ideas he thinks are good...]
