They make sense with the "old" style of coilovers, or for KW-type systems, but Ive seen them on coilover setups with independent height adjustment. It also looked like there was enough thread on the strut to just use the bottom spring perch to secure the spring.

Drift cars are a bit different, as they get air, hang wheels over curbs, transition off banks at high angles etc. These suspensions need more droop to take these kinds of loads smoothly, but still short springs, therefore they need helper springs and dampers designed to work with them. A lot of the cheaper coilover systems on the market (Sub $2k) aren't designed to work without spring preload.
It very much depends on how much stroke you need and what the ride height of your car is. This is why rally cars have super long dampers but still a pretty low ride height. They need the droop travel to absorb the impacts of jumps and ruts, but the dampers are sitting at half their travel at ride height.
