Or maybe... FastMail created JMAP, ergo they are the one with the best implementation.
Now Apple is working on moving iCloud to JMAP, and are working with FastMail as a JMAP production level service within mail.app.

The stock Mail app for iOS does not support JMAP.
Apple uses a proprietary IMAP extension that, until recently, any developer could use by generating a APNS certificate using a reverse engineered endpoint from macOS Server. They’ve since closed this.
Fastmail have had sanctioned access from Apple (via their own APNS topic ID) - https://www.fastmail.com/blog/push-email-now-available-in-io...
There were some changes last week to the JMAP Email Delivery Push Notifications[1], so that could be related.

How iOS Mail gets push inbox updates working with third-party IMAP servers is in the public since 2015/2016 if you look hard enough. That has nothing to do with JMAP the protocol inherently.
Your alternate theory doesn't pass Occam's razor given Apple's general behaviour. Do you have any evidence?

None, that's why I started with "Maybe...". I'm spitballing here and try to exchange ideas with other people interested in the topic to debate it.
I love every answer my comment received!

I know you said „maybe“, but this is how rumors begin.
I can not find any reference to Apple having any involvement with or interest in JMAP (as much as I’d wish so).
