The real question in my mind is if the "attic space" of learning a new tool and dragging it around everywhere is worth the convenience versus doing it The Old, Boring, Manual Way(TM). I suppose time will tell...
^^^ that is true enough
"reduces cognitive load"
^^^ that I have doubts about. I expect this would be highly variable between people, which leads to my question about the trade-off.
For those who are newcomers (say ten years or fewer) to the *nix world, it may well be an improvement. For those who have been using the standard-ish tools for 30+ years, learning yet-another-new-utility has a very high cost.
That dilemma would be irrelevant if the person taking backups is the same person doing the restoration (as will often be the case). My concern is along the lines of "what if this becomes a de facto standard?"
