So - if there isn't particular reason why there isn't generic attributes,
I'm wondering - maybe they will be implemented?
Those would be great for ASP.NET MVC action filters.

Attributes can be applied to generic types in the same way as non-generic types.
It allows efficient development without the need to incorporate or switch to C++ or languages with builtin template systems, if desired. Using generics and templates in C can also make programs more type safe, and prevent improper access of memory.
Use the IsGenericType property to determine whether the type is generic, and use the IsGenericTypeDefinition property to determine whether the type is a generic type definition. Get an array that contains the generic type arguments, using the GetGenericArguments method.
In C#, attributes are classes that inherit from the Attribute base class. Any class that inherits from Attribute can be used as a sort of "tag" on other pieces of code. For instance, there is an attribute called ObsoleteAttribute . This is used to signal that code is obsolete and shouldn't be used anymore.
I haven't seen any evidence of this in the 4.0 spec... so I believe the answer is "no".
