It's complicated.
In the UK at least that stuff got played in the same dj sets as the harder hardcore/embrionic jungle.
I like my piano hardcore with a bit of grit.
There was a real fork in the road circa 1993, where things split three ways. before that they all got played together in varying ratios.
I like it when it's really mental sample collage music. that's when the potential of the chipmunks etc gets really unlocked.
