Why would you replace it BiMap for BidirectionalMap? Peformance? Any 
particular bug?

We already have Immutable class implementations. Are Google ones any 
better? If so, why are they better? What do they bring new?

Thanks for the heads up but we're a bit wary of bringing in third party 
dependencies unless there's a very good reason to do so, specially to 
the core/ module.

So, if you wanna pitch third party library additions, please indicate 
clearer and more concise reasons to bring them in and we'll evaluate them.

Cheers,
