Okay, I just noticed the spaces missing and wondered if that clobbered that thing. You can also do some of that via wp-config but I think there’s some important caveats to doing that.

There are a couple ‘maintenance dashboards’ that might help ease the burden on some of that maintenance work.
Managed WP and Updraft Central are two I use together inside of a WordPress install I have that’s setup to automatically ‘call up’ each of my client sites daily… one at a time in a new tab.
That’s the dashboards I use to ‘ignore most all the updates’ and catch the sites being down when my clients insist on auto updates. <GRIN>
Jetpack is also somewhat useful but their uptime checking triggers a lot of false positives.
I also run a cron task from a commercial site for many of my sites… if they are down they will trigger a ‘red flag’ there. I mentioned that as you might want to trigger automatic updates from a crontask to control that better. I don’t know how, off the top of my head, but maybe via the Command Line Interface or some plugin.
Just some ideas… I get this way late when I start getting sleepy. Rambling!
