No, think about it. And I don't care if this was brought up.
The "other friend" is in the CoW. Explains Sora-Ven relations assuming he is the "other friend".
Explains why Axel changed so much in CO - he met Sora (also arguably why Sora didn't go around changing the multiverse - he needed CO?).
Explains why they can never find it - they're looking for a room, not a person.
Explains why Namine was born in CO if you wanna go CoW-CO relations - Sora sent her there at birth.
And this could yet tie in with Terra giving Riku the Keyblade - either to protect or break Sora should the need arise.
And wouldn't it be utterly fun if Sora and Roxas's Destatis actually took place inside the Chamber?
Some more bits and pieces of logic:
Seeing how the CoW being inside Sora would explain his Ven-relations, this leads to the logical conclusion that however the CoW ended up inside Sora, it happened during/after BBS, otherwise Ven couldn't have been "inside" it.
Let's assume for a minute Roxas and Sora aren't the only ones to go through a Destati - then what if that's the reason why aside from Sora, Riku and Mickey, there aren't any more wielders?
You become a Wielder by going through a Destati in the CoW. Only post BBS, that Chamber was sealed up or otherwise unreachable inside Sora!
