Summary

Our docs currently state that we're unopinionated about secret management. The ecosystem has evolved to the point where we should have an opinion.

Motivation

Supporting less-than-ideal secret management practices is 1) costing tech debt and 2) reinforcing anti-patterns. We should work on reversing both of those.

Proposal

Update the docs to state that our opinion is that 1) you shouldn't inject secrets via hydration, and 2) you should use an on-destination-cluster secrets operator.
