Anti-seizes with nickel and copper excel at high temperature service (think exhaust systems) which is not an advantage for bikes. I also think that introducing one or more additional metals into a galvanic mix may be less than helpful.
I think that threaded fasteners made of aluminum (cough, spoke nipples, cough) are a mistake in most instances, especially vs other aluminum parts.
I've always wondered how nickle antiseize apparently reduces corrosion. Everything I've read suggests its use there, but the very little of the chemistry I know would make me think otherwise.

I'm actually counting on that! I always prefer close fit rather than normal or loose for clearance holes. Most are oversized and the M6 will fit fine. For those that are actually sized more precisely, I don't mind expanding the <1 mm it would take.
There are probably the occasional items that have an integrated screw. Haven't used one yet though, so will figure that out if it ever becomes an issue.
