 "The user has the full control over the initial extensions table."

Does this option change that? Is this feature mutually exclusive or additive to
any "current control" a user has?

In other words, it is not clear to me if I can add this option and still
maintain any existing controls I may have.

If it is not and users need to make changes the user code becomes a mess of
version defines. Is that what we want?
