What's the rationale here? Are we expecting the embedder to need to override the
vibration provider?

[ostap, 2013/11/18 21:47:18]

Yes, it adds possibility to override vibration provider.

[Avi (use Gerrit), 2013/11/18 21:49:49]

That wasn't my question. Yes, it offers the possibility, but are you expecting
that you'll need it? I'd rather hold off on that until we know it will be
needed, rather than put it in and have an unused override point sitting there.
