They keep saying "Cloud-Native Developers" in a bunch of titles and the text, but I'm pretty sure this is mostly going to be Azure-cloud focused.
Since AWS only supports LTS versions, a lot of things have been stuck on dotnet6 there. (Unless you install your own frameworks or docker or own ec2 images or something) - But no proper native cloud support for a lot of dotnet7 from AWS
For example, Lambdas don't natively support anything besides dotnet6, and dotnet8 is still scheduled to be released (Mentions February 2024, but used to mention January 2024, so who knows when it's actually going to be released)
Since dotnet6 and dotnet8 were LTS, I doubt dotnet9 is going to be as well, and is going to be STS again. So all the Cloud-Native stuff in dotnet9 is pretty much going to be Azure
