No, it wouldn't help. If the developer's system is compromised, the rootkit could see and intercept every action. The rootkit would simply wait for the developer to sign a commit, and then apply that signature to a different commit. The fact that the developer also had to enter a token from a smartcard or get her iris scanned is no defense if someone else owns the developer's machine.
