In my experience some people use "pair programming" to hide their insecurity and incompetence.

I concur, but consider ProxySQL instead of HAProxy. Percona with XtraDB/Galera failover fronted by ProxySQL is very resilient and performant.

That orchestration technologies like k8s and OpenShift generally make services less stable and less performant. IMO not an unexpected consequence, but clearly an unintended one.

I guess this would not happen if people were to use the above technologies with stateless services only, but they don't because the majority of articles, blogs and documentation on the subject leads people to believe that using network based storage for your io intensive state full services is good practice.
