Hi, I am one of the people writing and coding these standards at Fastmail. There are IETF standard drafts for JMAP calendars, contacts and tasks in the works (not just by Fastmail). We aim at publishing them in 2023. You can check the progress in the IETF calext and jmap working groups and we appreciate any input on the mailing lists!
