Generally, companies that have AI integrated to this extent have no engineers remaining who could have made such things impossible.

It starts with automating backups that nobody verifies for years, then continues to off-shoring all development to the cheapest contractors that nobody actively manages, handing over all "keys to the kingdom" to cloud providers, culminating with elimination of 80% of infrastructure and engineering staff in a mad dash to cut costs at any cost. At that point giving AI agents full access is just icing on the cake.
