Yeah, this is a good summary. There should be room for experimentation in isolated, non-production environments if the engineer in question is trusted and can propose a hypothesis better than "I think this will make my resume better". That stuff shouldn't be rushed out to prod without thorough vetting both internally and externally, which, much to the dismay of junior engineers (and not-so-junior engineers with bad judgment), often means letting a tool age a little bit before you bet the company on its stability. Unless the tool truly revolutionizes your particular line of business, and let me pre-emptively state that there's a 99.99% chance that it doesn't even if you think it does, there is no harm in letting other people be the guinea pigs.
