Yeah it just seems like Fender wanted to hinder the aftermarket, otherwise it's mostly a solution in search of a problem to me... The cut sides are nice, but I just buy vintage bridges that have that done by third party sellers. The compensated brass barrels are nice, but nothing new. Adding two mounting screws to the front for better bridge to body connection is a common mod. The only real "improvement" is the wider width to prevent the "butt crack", not sure Fender needed to design a whole new bridge just for that. I think it really comes down to deliberate incompatibility with the vintage bridge aftermarket.
