Yes it would. And that’s where you balance how much effort into adding back those updates or syncing them with the default settings site.
I’m not defending Divi. I’ve had stuff happen with all SaaS at some point or another. But multi sites are a pain and not worth the hassle IMO. I don’t run them anymore. Too many chances for software issues.
But here you are and you need to get to the other side. So weighing the time options are all you can do.
