Babalon makes so much diverse music almost like RDJ, from ambient to most hardcore noisy stuff and he was mostly tied to Alec Empire's Digital Hardcore genre. Does he also make breakcore stuff? Probably.
For me personally, breakcore term was always simple: break = amen jungle beats, snare rush etc. + core = gabber kicks (plus some stolen samples from multiple genres, films etc). If someone no longer uses these, it's no longer breakcore stuff imo. But fuck it, it is not important, it's the music that matters, not crappy labels.
