I see the value when running e.g. home instrastructure on some old laptops or other non-critical stuff. Most people have NAT at home and thus whatever services they pull and listen in their local network aren't exposed to the outside world, and they can enjoy mopidy/NextCloud/whatever without going through a lot of hassle setting it up.

Of course once we come to enterprise environments the opaque build/deployment process is atrocious.
