Yes, and if you read the thread in which he talks about it (oh right, you probably don't speak Japanese), he says they are considering adding it in a way that doesn't take away from the experience.

So if Yoshi-P is smart he will do one of the following:

-Add it as auto-jumping
or
-Add it as a limited manual jump

And since he's been doing a good job so far, I'm pretty sure that's what he'll do.
