I think there should be a middle ground. On the one hand, what you are saying is correct for many projects/companies and they might be needlessly burning money on tech. On the other hand, these solutions (devops, CI/CD, version control, etc...) were made for a reason. At a certain scale, the old ways break down badly.

Would you suggest that version control (git) is over-kill? You can still use FTP to upload your website.
