Mate, we're not at each other's throat, we're just debating calmly. It's ok to disagree on something. I know some users like to call each other "retard", "illiterate" or other unpleasant things when they disagree, but that'd never happen with me.
What's so unsettling about an advanced application of CoO that'd detect dormant CoC? I know people in Marineford couldn't tell Luffy had it before he actually used it, but aside from an obvious retcon due to the fact haki wasn't a fully fleshed out concept at the time, you can rationalize this by concluding that they just didn't bother using that advanced application on Luffy. They had no real reason to so, after all.
And once again, even if Sanji harassing Gaban was a gag, him expecting to get anything from him only makes sense if he can also sense dormant CoC. I doubt Sanji thought he could use it already.
