I feel this is much more applicable to SRE and Ops Engineers where performing, rehearsing and practicing is much more applicable.

Where I work, SRE work on their own tooling that is synonymous to releasing. They rehearse in the form of conducting weekly drills like failovers. The rest is similar to what is written in OP.

For releasing, I wasn't thinking so much about the actual act of deploying the code. I meant getting code to a state where it's ready to be shipped and used by customers. It's important to break yourself out of the perfectionist tendency to just keep improving code and never releasing it.
