Yeh I often go solo and after a few experiences, particularly if its unfamiliar, I try to make sure to have a charged backup device with routes etc loaded.

Similiarly I am not arguing against people using a map and compass, but I think the current advice which is entirely focused on map and compass with little guidance for phone users (which if it exists, is always caveated) has a lot more to do with outdoors peoples notions of technological purity and less to do with public health

I think we're actually in mostly violent agreement,

The ten essentials or whatever you want to call them are probably rather outdated.

I still think throwing a map and compass in your pack and having at least a bare minimum knowledge of how to use them is useful insurance in an unfamiliar area. But understanding mostly simple processes/backups for GPS is quite important as well. Details vary by circumstance/weather/etc. but simple steps in terms of downloading maps/having backup chargers/even a backup device/etc. are useful and I don't think have generally made it into basic hiking safety advice.

It's really hard at this point to credibly argue that "the ten essentials" don't include a smartphone.
