I don't see too much value on that. We want to encourage people to stop
to use the deprecated methods. So if there is a working implementation
of the new method, I don't think that it is worth to ensure that the old
methods work.

And in fact, probably that mapping is not possible. The new API is more
simple (on purpose). Just one method (vs 3) and 5 text granularities (vs
7), so I don't think that we can express all the old API combinations
with the new API. And as I say, I think that we also don't want that.
