Absolutely excellent advice.

I would start by getting consensus on process. Hit up the main engineering chat channel and describe the issue you want better. "Deployment is painful and bug prone. In order to get code to production, first we have to..." Of course use neutral, non-judgmental language - this is the process that has emerged, no one's fault. This is an engineering problem to be solved. Next, ask for thoughts and opinions. You could suggest your own if you think it will help, but it's about building consensus. Just starting these conversations can be enough sometimes. But you can take it to the next step and actually build the tools that are suggested.
