Mob spawn is too frequent at nights

Mob spawn is spinning out of control, it seems like there was used to be some kind of interval on 1.13.2 that allowed more even distribution of mobs across a rendered area, but now it feels like that interval is either too short or removed

steps to reproduce:

Enter a world on both versions, enable cheats, kill all the mobs by either tping them to the void or by /kill. watch the spawn rates

this can be very unintuitive for new players as nights become hellish to survive at
