Why does my TextureView no longer become available?

[KRA2008]

I migrated to MAUI from Forms recently, and I decided to shim my huge and complex custom renderer that interfaces with the platform camera rather than migrate to a handler. This worked great for the most part, because all the required callbacks and wiring to connect the platform code to the cross-platform control appears to get invoked as needed. This is on Android by the way, and my custom renderer inherits from ViewRenderer<CameraModule, View>, where CameraModule inherits from ContentView.

However, now I find that the TextureView that I have relied on for years no longer becomes available. My understanding is that that means it never gets attached to the Window. I inflate my axml layout that contains the TextureView, I attach the callback handlers, and then I add it with AddView, but it doesn't work anymore. I also tried doing the same using the SetNativeControl method, even though I haven't had to do that before, but that doesn't seem to change anything. Why would this be?

My project is at https://github.com/KRA2008/crosscam and the branch that shows my current frustrated state is mauiMigrationGOODer.

Edit: I went ahead and grabbed the WindowManager and added my view to the Window myself, and that resulted in my callback code being invoked - the TextureView became available - but the layout is all messed up, probably because I'm giving it bogus LayoutParams. So why is the TextureView not being attached to the Window for me?
