This is the way it has always been. The only thing protected is the scripts.
Things like images, properties and custom properties are not. Given that:

1. You can encrypt and decrypt the custom properties and images of a
protected stack from within the protected code of the stack itself.
2. Having these elements unprotected allows for updating the protected stack
without having to unlock and relock it and therefore can be done on a user's
machine. 
3. In the case of a library stack, the stack can use itself for storage and
be saved. 

I don't see what you are requesting as an advantage or desirable.
