I think that’s a fantastic practice. I always struggled with that too when boarding b/c I very often didn’t see my horses until after ‘working’ hours. And I work a lot. Plus, for all the reasons mentioned upthread, barn staffing standards began to fall so I would have more to communicate that I just didn’t have to before. So I’d text more than I liked but tried to limit it to basics and always indicate a ‘like’ only or no response was needed.
I think what I know now is that when the basics are covered (water, food, shelter and (relative) safety), there’s probably nothing else I’d ask a BO to do for my horse in a regular boarding situation anymore that didn’t directly impact her health. As an example, I’m kind of mortified I ever worried about blanketing changes for my non-clipped mare and young horse in NC. Or whether someone forgot to feed their non-medical supplements that day.
She and my young horse have been blanketed two days all year? They’re fat, happy and its quite literally not a problem. I used to worry quite a bit about my older mare in her stall at night and check the weather constantly to make a blanket decision.Totally unnecessary. 
I’ve always had more success with modifying myself, leaving or modifying my horse’s management than the barn’s program over the years. Horses are just really hard on people and it’s so easy to lose sight of that when you’re not doing the work every day. I’m guilty of that for sure - it’s a tough position. If I were boarding now, I’d likely try to find/hire a private groom or call my vet and find someone who wanted a few extra hours a week to personally check on my horses if I were still traveling and working for long periods of time away from them.
