Hi I see you’ve asked that question a few times now, I assume it’s somewhat rhetorical but I’ll reply, Roon’s position has not and imho will not change.
Roon are a selfstated unapologetically opinionated company, they have their vision for the product.
As users we can make suggestions but being frank Roon will always follow their own path.
Personally, I think it’s wise to have a fall back alternative, irrespective of the Roon requirement to be online, equipment breaks, drives fail, etc. etc.
Contingency Examples, see my linked post …
