Motivation/Principles/Requirements extensions to Archimate - Archi User forum:

"(ArchiMate® Extension for Modeling and Managing Motivation, Principles
and Requirements in TOGAF
A White Paper by: Dick Quartel, Wilco Engelsman, Henk Jonkers)

specifies a Motivation aspect, and adds the following objects:
Stakeholder, Concern, Assessment, Goal, Principle, Requirement, as
well as some new relations. This would make a great addon. "

Great ! If such an extension is added, that would allow me to use only one method instead of combining KAOS and Archimate in the eRRA methodology.
