Yes the knowledge revealed in SBS is "canon", but in this sense I mean as in written into the story and played out. Its "canon" knowledge that Monet and Sugar are sisters, but this fact hasn't been mentioned or acted on in the manga. Its technically "canon" that Luffy can make his penis stretch too.

^And I'm certainly not trying to argue that, I'm just saying that who he isn't shouldn't be COMPLETELY discredited for the simple fact that he was made for a non-canon movie. I completely understand why he's noncanon up til now. We shouldn't assume that Kuzan, Borsalino, and Sakazuki simply became beasts out of nowhere, someone had to teach them. The fact that it was Z is completely inconsequential to the storyline up til now, but does that not give who Z is as a person THAT much more significance? Think about it, whoever this 7th Shichibukai is, they're not going to be just some random person we've never heard of before. There has to be a legit reason they became a Shichibukai (even if Buggy isn't strong, you  have to agree their REASON for making him one is still legit). Shichibukais are always people of major influence, or always people who have done something of major influence. So whoever this person is, they've gotta be one bad MFer. Cutting the arm off of a frickin Admiral who had so much influence in the Marines could def put one in that discussion, and would certainly be a decent reason to have been "that man I told you about earlier". So the fact that Z isn't canon isn't lost on me, I'm just saying who he is as a person is certainly significant enough for their lives/actions to have ripple effects on the canon storyline.
