Is it possible to add blacklist rules instead of whitelist when defining sandbox safe policy?

I like using the allowFunctions for functions that I allow, since I believe this should be a very limited list. However, when it comes to allowProperties and allowMethods, I can have an infinite amount of objects, and it's a headache to define each of them, when they are alredy safe, except for maybe 1 or 2 that I would like to block.

For anyone else wondering about this, I realized that it's very easy to extend Latte\Sandbox\SecurityPolicy and overwrite isPropertyAllowed and isMethodAllowed.
