Let's be honest. Who is seriously using Ti.Yahoo API's these days? I guess some, probably even a lot. But not enough to reserve a seat in the SDK for it. That's why we should remove it from the core and provide the exact same classes / functionality in an external module.
- Move to external module (ARC-based, move docs to module docs, link module docs to SDK docs
- Deprecate it in 6.2.0, link the module to the core (like APSHTTPClient)
- Remove from Core in 7.0.0
