The status of simultaneous support for secrets, encrypted credentials and multi-environment encrypted credentials is confusing

figuring out ways to smooth migration paths so that we can get back to a single recommended mechanism (with support for other options, such as env var config).

This would be great… One of the reasons that I love Rails is because of its Convention of Configuration mantra, and secrets along with the front-end methods right now seems to be the main exceptions to this rule.
