I have no idea what that is, never heard of it in fact. But you're kind of proving my point.
If you think it'd be great to live in a world where 1% of the population listens to rock music, and 0.1% are listening to music written and played during their lifetimes, cool that's great for you.
I mean we're at the point in conversation where we have to establish what dead even means?
I'd argue the reasonable position would be when the genre becomes inactive and the bulk of popular content is written by people who are dead. We can debate what the ratio points are but this is already established in things like linguistic.
Latin is a dead language, doesn't mean no one reads it latin studies of one kind or another is actually relatively common, dead just means nobody is speaking it.
EDIT:
My definition of dead is going for a walk on Friday night in a city of a half million people. I went all over down town looking for a band any band, any kind of live music. After asking every other bouncer etc, I kept getting pointed to the Karoke bar, which occasionally will have live music.
20 years ago, my home town of 6,500 people would have had a atleast 1 live act playing, likely multiple.
I get if you live in LA/New York/whatever you think otherwise. But when a ultra white/suburban town in arts crazy Canada doesn't have any rock playing you know the genre is dead.
