Totally understand the goal of "set and forget". I love set and forget.
But for critical path things, I personally find that a weekly routine of checks is a good thing to do. YMMV, but I was just pointing out to people that this works well for me. (And likely will work well for the unsophisticated computer users who are likely to have developed such non-computerized routines in their lives, which are the people we were originally talking about.)
100% OneDrivification is classic enshittification making things worse by drawing people into the prison walls.
(Another example is the fact that this kind of hand-driven "backing up texts" is to my observation nearly impossible. - if anyone knows of how to do this easily, I would love to hear it.)
