What might be wiser is to turn the idea on its head and ask why other traditional instruments are disappearing. I don't think there are any hammered dulcimer players left in East Anglia now, at least not in an organised body. They don't cost much more than a decent guitar and are far more versatile in transposition. Julian Goodacre's English pipes seem to have been caught in an Early/Mediaeval Music backwater. Low whistle players are at a premium. Yet the EFDSS runs ukelele classes in CSH!
