I think that any kind of “modern ops” necessarily includes coding, even if there isn’t a ton of Python or Rust being generated as part of the workflow.

Kubernetes deployment configurations and Ansible playbooks are code. PromQL is code. Dockerfiles and cloud-init scripts are code. Terraform HCL is code.

It’s all code I personally hate writing, but that doesn’t make it less valid “software development” than (say) writing React code.
