You'd think that, except the other mobs still spawn en masse.
Even in SP, in a buffet world of deep lukewarm ocean, on hard mode, I only find a small few spawn.
Waiting about five mins starting at 14000 ticks into the day/night cycle and first killing all entities, I got 7 drowned.
Waiting about 5 mins on a small stone platform I placed above the ocean after the drowned test, and again 14000 ticks and killing entities first, I got 12 zombies, 8 creepers, 6 spiders and 11 skeletons.
