Well, that kind of decisions demand injecting a node so there could be
potential interference (as with more mechanisms that carry status info
around for a second pass).
Anyway, maybe someone else benefits from the extension.

But I'll not enable it to the code as it's not used anyway (maybe
sometime a module).
