I'm assuming this is hand-rolled? It doesn't really matter, but it would be more
accurate to say M38 I think

ppb_nacl_private_impl.idl is versioned at M25. I could bump them both to M38, I
suppose, but it doesn't really matter, because neither of these are normal
versioned interfaces.

I think in theory both should be bumped, but yeah, doesn't actually matter.
We've not been bothering with it up to now, so ignore my comment.
