Summary:
The UIAppearance API is pretty cool, but requires a lot of boilerplate duplication.
To consolidate global styling efforts, it would be very helpful if instances of the private _UIAppearance class responded with YES to -isKindOfClass: if the class, the appearance is a proxy for, would.
I.e. basically, _UIAppearance should override -[NSObject isKindOfClass:] as:

- (BOOL)isKindOfClass:(Class)class
{
    if ([super isKindOfClass:class])
        return YES;

    return [class isSubclassOfClass:[self _CustomizableClass]];
}

Steps to Reproduce:
Run the tests of the attached sample project.

Expected Results:
The tests pass — and would, if the list of UIView (sub)classes was more comprehensive.

Actual Results:
They fail.

Regression:
