I think letting it rot on features was pretty much the easiest course to eventually remove it without anyone accidentally ending up in the middle of a Streisand effect while defending a renaming. I really liked ReiserFS way back when but there are plenty of other FSes to choose from or choose to improve so there's little reason to deal with that baggage.
