Static class members should be static by default?

Sample code:

public class MyStaticClass {
public static string Property1 { get; set; }
public string Property2 { get; set; } // compiler error
}

This is a very intentional design decision of the language. If you started out designing a static class, then in a later version made it non-static, without the current restriction all your members would now be instance members and all your callsites are broken.
