Was not aware they scuttled 1,200km ka/ku band constellation and corrected in another reply. Either way, per your citation, the current plan still puts 10k+ objects in 400km+ orbits where debris hangs around for much longer. Primary point still stands - starlink isn't limited to sub 400km constellation and kessler syndrome risk for higher orbits is real (risk increase not linear). Especially, if starlink plan to go to 42k above currently planned 30k, most are going to be 400km+ since sub 400km orbits are taken. Unless UN/ITU increase slots, the amount of sub 400km slots are fixed, and expanding megaconstellations including future starlink expansion is going to be satuating orbits with multi year / multi decade decay.
