If the switch doesn't want to come back up, I for one would rather know about it following a scheduled ini, rather than find out about it by accident after an automatic ini, possibly during working hours leading to an exposure.
Not coming back up is a sign that something is wrong, and attention can then be given to the reason for that.
Sure it can sometimes need a little assistance getting back to it's feet after an ini or reload..
There are pro's and con's to scheduling regular ini's. I've heard of customers who carry out reloads, even when nothing is wrong, every few months. And there are customers who would bend over backwards to avoid them, sometimes taking remedial measures to avoid an ini that exceed the pain & risk of the initialise itself.
From freeing up stuck tasks to clearing out registers and clearing status flags and much more, the M1 ini can be pretty useful. I tend to go for reloads more these days, though.
