ReFS boot support for Windows Server 2022?

Senior Member

Two years ago, I predicted that Windows Server 2022 will support ReFS boot, just like Windows 8 started to support exFAT boot that year. 
Now, The ReFS of Windows Server 2022 Preview (Build 20348.1) has been upgraded to version 3.7, and its bootx64.efi already natively supports the ReFS boot feature. As shown in this screenshot, I have successfully installed and booted Windows system in ReFS partition. 
But its bootmgr still does not provide ReFS boot support. Is there any plan to add ReFS boot support in legacy boot mode in the future?
