[Feature Request] Add the opposite option to reservedNames (forceTransformProperties?)

[SukkaW]

OK, renameProperties is dangerous and it can break the code. With reservedNames it is possible to prevent some properties from being touched. So what about we provide a list and only the prop name in the list should be renamed?

In short, besides a blacklist (reservedNames), I'd like to have a whitelist as well.
