No see, some guy from Heroku wrote a blog post about comprehensive build artifacts so now that's what we have to do. What don't you understand about comprehensive build artifacts? Maybe we can get on a long, long, long call to discuss how I'm right and you're wrong, I did work at $HUGE_COMPANY after all.

We can't possibly do things the wrong way, no matter how dumb our current practice is.

Immutable-ish builds are a great idea, but you should fix why on earth it's taking 2 hours for a Docker build :)
