In addition to local "petnames" and self-proclaimed "nicknames", we may want to support "edge names", or "shared names which users give other users and then can share with others to help discovery and corroborate who a user is."
For more on this, see https://spritely.institute/news/two-petnames-papers-are-released.html and especially https://spritely.institute/static/papers/petnames.html
This type of feature would allow for a more general form of the existing
domainsslot, whereDNSwould merely be one edge name provider.
