Discarded Features in Scope

TBD.

Proposed Ideas

For previous discussion there is a recommendation by Google/Apigee:

to focus first on defining an extension to describe technical concerns: SLI and SLO aspects as a clear technical concern and
to keep SLA (as a business contract) out of the scope for a later extension.
