Do you promise to come back and tell us the story about when someone went on vacation and the certs issued on a Thursday didn't renew over the weekend and come Monday everything broke and no one could authenticate or get into the building?
I applaud you for sticking to your guns though.
And the conventional wisdom for application management and deployments is - if it's painful, do it more. Like this, applications in the container infrastructure are forced to get certificate deployment and reloading right on day 1.
And yes, some older application that were migrated to the infrastructure went ahead and loaded their credentials and certificates for other dependencies into their database or something like that and then ended up confused when this didn't work at all. Now it's fixed.
