No argument from me - just presenting info.
Bleeding might reduce risk. Generally the Infiniti manual is written conservatively. If they don't recommend it, then it really isn't necessary. Kind of like using an oil catch at NA. Good to have, but not required. Also, brake fluid is flushed periodically with normal maintenance which should catch any contamination long term.
They do recommend bleeding when bolting the caliper back to the torque member, even if you never removed the brake lines from the caliper. Why it makes sense to do it for this reason but not the pads - I'm not sure.
