[Revised after reading the code more carefully.]
I'd like to use Flask sessions with a few tweaks:
In the absence of direct support of these features, I think I can accomplish them with a SecureCookie/Session subclass. It looks like I can make Flask use my subclass by overriding Flask.open_session(), but since the existing method contains slightly more logic than simply instantiating a Session, I'm concerned that overriding it might introduce strange behavior with future versions of Flask
Would you consider exposing an official means of using a custom Session/SecureCookie class? Maybe even turning some of the above tweaks into Flask configuration options?
This can be done with SessionInterface.
