What is your support matrix for the fabric version of this code?

For 0.74 specifically we are back pointing large chunks of our fabric work. The APIs are all marked experimental, and so are not guaranteed to be stable.

In particular microsoft/react-native-windows#13319 will apply this rename to 0.74 too. Do you want to do a patch version check to have the code work on older 0.74 versions, or just update the code for 0.74 too?

The APIs to size the Island also changed a little while back, so I dont think this will compile?

Since this is experimental, I don't think we want to support more than the very latest. Since you've backported it, I'll just use the new name directly.

I can't even get latest nightly to build atm so I will have to wait till a new 0.74 is published to verify.

Apart from microsoft/react-native-windows#13344 and #2085, I'm hitting these build errors and I have no idea why:

 × Building Solution: Package.appxmanifest(51,27): error APPX0703: Manifest references file 'Images\SplashScreen....
 × Build failed with message 2:6>Package.appxmanifest(47,9): error APPX0703: Manifest references file 'Images\Square150x
150Logo.png' which is not part of the payload. [D:\react-native-test-app\example\node_modules\.generated\windows\Win32\R
eactApp.Package.wapproj]. Check your build configuration.

And if I build from Visual Studio:

3>Package.appxmanifest : error APPX0703: Manifest references file 'ReactApp\Microsoft.ReactNative.dll' which is not part of the payload.
3>Package.appxmanifest : error APPX0703: Manifest references file 'ReactApp\ReactNativeWebStorage.dll' which is not part of the payload.

It builds successfully, I think. It's just the packaging that fails.

Merging this for now since the packaging issue seems unrelated.
