For what it's worth I reckon that it probably is worth preserving as is any work of art. I do disagree with the 'this is the way this must be done' faction though.
Lets look at and listen too how it used to be done and then do it in our own special ways. That way it neither detracts from the original or keeps us in a rut.
After all we preserve the old buildings while still building new. We admire the old masters while appreciating the modern. And we love the classics while still groovin' on down to the latest sounds... Don't we???
