Well, the list is still a distraction from the real work an architect can do, which is bring projects together and build foundations for successful projects.
The reality is you can claim to be in the REA. Anyone can. If someone is impressed with that and hires you, then so be it. If they are smart, they look into your history and see all the awesome things you’ve done, which hopefully speaks about your legitimacy. A list will not do that, at least not without major editing. A list of people’s names by itself means nothing without their project history.
Why manage a list of everyone’s resumes, when everyone can just manage their own resumes?
