That's just part of growing pains. I imagine that when Microsoft finishes their long term plan for .NET the layers will basically be:

.NET Core - implements .NET Standard.

Everything else is layered on top of .NET Core: .NET Framework (Windows), Xamarin (Linux, MacOS GUI, Android, iOS).

So basically everything in use will support .NET Standard.

Retconning is a bitch :p
