weird thought in head someone help me out

[DierwulfBL]

well about a month ago i was checking my brakes to see if it was time to slap the metallic pads on, it wasnt time. I did however notice that my rotors were grooved quite badly, but also the brake pad had the exact same groove pattern so that the grooves interlocked. I was thinking seeing how the grooves lined up wouldnt that in essence give the brake rotor more surface area to help stop? like if you straightened out a ^v^v^v^ youd get -------------------. Using the same logic if this was the case and it worked, why dont they make brake rotors with some beast grooves with matching pads? or am i completely lost in my head thinking this? help me out im sure theres a reason this is bad/wouldnt work.
