Thanks. I wasn't worried about Server 2022 Standard or Server 2022 Datacenter (both are listed). Server 2022 Essentials is the one missing from the list. Since that's a more obscure OEM only SKU from Microsoft, I was wondering if the omission was intentional or not, and if anyone had any experience with it. (The lack of response seems to imply there's no experience out there...)
I just verified this internally and we have not qualified Windows Server 2022 Essential and therefore it is correctly not listed in the SCL.
This is because as you already mentioned above a more obscure OEM only SKU from MS and the availability of the installation media itself.
