"JMAP is intended to be a new standard for email clients to connect to mail stores. It therefore intends to primarily replace IMAP + SMTP submission. It is also designed to be more generic such that it can be extended with contacts, calendars in the future (replacing CardDAV/CalDAV). It does not replace MTA-to-MTA SMTP transmission."
Who uses or supports it?
Cyrus IMAP and Apache James are the notable ones here: http://jmap.io/software.html
OpenPaaS is an open source Entreprise Social Platform which is led by LINAGORA (which has more than 150 employees)

http://www.open-paas.org
OpenPaaS is using Apache James. And you can see JMAP used in the code:

In this video: https://www.youtube.com/watch?v=2QZIi3EO6rQ , Benoit Tellier explains why they decided to invest in James and JMAP (among other things). LINAGORA has 5 full time employees which are devoted to the project.

FastMail started this initiative:
"JMAP is FastMail's protocol with the warts removed. We leverage existing standards like HTTP, JSON, and native push channels on platforms which have them - making it easy for developers to work with."

Thanks!
Don't hold your breath on Roundcube Next.
Now is a good time to start the implementation:

Thanks!!!
And it's an official RFC8620 now.
The list of supporting servers and clients are listed here.
There are some clients supporting only this too like ltt.rs
