I have the same issue, but with the opposite conclusion: if this were integrated with cp/mv/dd, I wouldn't be able to rely on getting the new versions.
But since it is separate, I can install it where and when I need it, perhaps with the transfer already in progress. That might be hard for IoT/containers, but do I really need to see file copy progress in those kinds of places?
Good point on updates. But if Debian pulled in latest every 2 years (Debian release cycle), wouldn't that be enough. I can't imaging improvements being so urgent.
Also, agreed on the need for this on IoT stuff. But it's about muscle memory. I want to type the same way on. all devices. Not "oh, I'm on a server, use this command. Oh, I'm on an IoT device, use a different command"
