Comment 6 for bug 1100220

I agree with Mark here.

The review proposed as (WIP) is meant to be read as a POC / start idea of how it could work. We should definitely find a way to support both cases or at least a way to update credentials when / if needed.

I suggested on gerrit (on some review comment) to write a blueprint for these changes and use that as reference for addressing all these bugs.,

The other thing to consider is that this issue has an impact on all store backends.
