Why doesn't new WSA Reflection API contain met

Question

Consider properties for example.

In old API I could call Type.GetProperties(BindingFlgas.Static | BindingFlags.Public);

But with TypeInfo I have either DeclaredProperties or GetRuntimeProperties() which return PropertyInfo instances.

But PropertyInfo does not contain IsStatic, IsPublic properties. To know this I first need to get Get or Set-method and check its properties.

It is said that new reflection API is more sound in architecture and performance ways.
But It's hard to believe in it. With example given above should I care about performance? May be I am missing something important in new approach?
