I think it's more likely a trust issue. He didn't trust the other devs to push things directly, but ofc he trusts himself. I do this with somethings myself. But I also do the inverse, where I don't want to trust myself so I setup a bunch of checks and tests to save my future self from my present self

I think when you're the 'architect' or know the full stack very well, to where you fully repl/grok it and occasionally need to do hot patch type work, the former approach is nice. But, my brain has limited memory and time erodes quickly, so I also know when to rely on the latter approach and I try to do it as much as possible
