> 2. Always be releasing...

A good argument for this is security. Whatever libraries/dependencies you have, unpin the versions, and have good unit tests. Security vulnerabilities that are getting fixed upstream must be released. You cannot fix and remove those vulnerabilities unless you are doing regular releases. This in turn also implies having good unit tests, so you can do these builds and releases with a lower probability of releasing something broken. It also implies strong monitoring and metrics, so you can be the first to know when something breaks.
