Settlements have very specific spawning conditions to ensure that they don't mess up the terrain too badly. It is my suspicion that the terrain of classic mode is far less likely to meet these spawning conditions. It is also my understanding that the current spawning rates are very high, so high in fact, that if the spawning conditions are met, it almost certainly spawns a settlement. So I suppose what you really want would be for the spawning conditions to be less specific, right?

Just out of curiousity, if classic mode isn't providing you a suitable experience, why not play on normal mode?
