Has x:bind in WinUI 3 effectively killed commanding and converters?

[greatoceansoftware]

I know commanding and converters have been a staple of MVVM pattern and XAML interfaces, but it seems like WinUI 3 is moving away from those, particularly in terms of the functionality offered (direct binding to functions and events) and seemingly encouragement in the documentation to use them instead of commands and converters.

I'm in the middle of refactoring a WPF application to WinUI 3, and after writing several XAML pages, it looks like it's going to be possible to avoid commands and converters altogether. So is it an MVVM sin to wholly replace commands and converters with x:Bind functions?
