One of the first things I did in my last job was shift processes like this off my team's computers, aside from the security ramifications all it takes is one dumb mistake, one up-arrow too many, one didn't-read-the-whole-line, and now you're doing something to production by accident!
TBH CI does not prevent this kind of mistakes. I've seen people triggering the wrong CI pipeline.
I also did that, for a team deploying smart contract on chain from local.
It took a couple months to get the pipeline out of their laptop.
Worth it, yes, as we found interesting things in there which explained why they were so reluctant to deploy upgrades.
