Six months ago I would have argued with you, but currently doing a MAUI transition from a Xamarin Forms app, and you are very right.

I wish Avalonia UI's mobile solution had had Navigation sorted a year ago when I proposed that we needed to do something with the XF EOL announcement. I had a POC with it working well enough, but sadly it was "too much work" to migrate the rest of the app. Now with MAUI we have realised that we are probably doing just as much work anyway, and it is seriously half baked as an ecosystem.

Thank you for this comment. Trying to sort through the mess of GUI frameworks for .NET and other languages is difficult.
