x:FieldModifier

Hi,
Is Xamarin.Forms going to support x:FieldModifier to generate publicly accessible ui element fields?
To put my question in a context:
I'm trying to use Xamarin.Forms with XAML from F#.
Because class generation from XAML is not supported for F# projects I wanted to try mixed C#/F# approach where
C# projects contains XAML and generated class. F# project presentation logic.
