Well, true...sheeple are everywhere. I'm not one of them. 😉This is all well and good but pretty useless advice when one has other Apple kit. For example, updating the Apple Watch to 4.3 is a no-no under iOS 10.x (at least that's my presumption since I can't even do that with 11.2.5!). When I got High Sierra on my MacBook I had to also have the latest WatchOS on my watches.
So, in isolation fine - nice idea if you can do it, in reality, when one has the ecosystem, one finds oneself hamstrung...
