The only information the hosts map has to go on is the export list received from the server. There is no way for autofs to know that /exports is the global root from the mountd exports information. It only knows that /exports is an export and neither does it know what NFS version the server may offer for this mount. That information just isn't available. As I said, I thought in recent Fedora releases (not sure now when this should have happened), that mount <server>:/exports /<some mount point> and mount <server>:/ /<some mount point> should both work and mount as NFSv4. Correct me if I'm wrong but your point is that it is mounting as NFSv3 so perhaps we should log a bug and see what the experts have to say on this.
