Allow Scoped values that do not implement IDisposable

[PrimaForge]

I would like to use the ScopedCache as a "While Scoped values are in use it will not be removed from the cache. The value does not have to be IDisposable." Is there a reason for the IDisposable restraint?

I would assume the value could be checked to see if it implements IDisposable and dispose the value if necessary. Of Course, I could create a Disposable wrapper, but Lifetime is already a wrapper I Would prefer not to create yet another wrapper if the constraint is no necessary.
