It's not a vague "UNESCO listing" in the same category as or competing with built heritage. It's specifically being recorded as intangible heritage, which is a category that covers a lot of interesting traditions, many fairly humble, such as craft techniques.
This seems appropriate. My area has had a big outdoor traditional folk music festival for nearly twenty years (it ended pre-COVID though due to rising costs) so I've long had an appreciation for things like that. Irish and Acadian music, blues and jazz, sacred steel, Japanese drumming, Tuvan throat singing...there's a whole wealth of art out there that has historical and cultural importance, but will never be marketable in the mainstream. It's important to record and promote that.
The Demoscene fits right in, as a short lived subculture that grew out of a radical democratization of technology.
