Right on! In addition I feel that #SocialHub community - where #fediverse technologists come together to evolve the open standards - is the best place to direct such questions to.
Better than toot threads, which are fleety and easily missed, the community forum is best for long-form discussion and serves as knowledgebase + archive.
Best-practice IMHO: Always point people to SocialHub -->

Another easy thing to do is tag the @activitypub #guppe group.
