Supported Monterey and OCLP Sonoma on the SSD a world first?

[iMac'd]

I have evidence from one person but it seems extraordinary that there are so few (ie. 1) who have published info. Is this because (as I'm finding) that it's difficult if not impossible to do OTA updates that don't get degraded by OCLP's control of the EFI? Using a 16,2 iMac with SSD only and the OS's in separate containers/partitions.
