I still don't see a compelling reason not to extend existing functions with a third argument. Or are we talking about deprecating them in the future (like remove their mention in the docs) and have the new names to replace them, with the new behavior as the default and the extended call convention as the old behavior? I'm not sure about that, so I think extending existing function is ok. Or we would have to have the new functions work well with other types too, so that it's compelling to move from the old ones.
