CB.13:5.5 - Shared practice without shared government
Independent repairers use the same published technique and send occasional corrections to its maintainer. They have no joint budget, common service promise or need for decisions binding the users. The maintainer controls the publication under its actual arrangements; each repairer controls their own practice.
Creating a council of all users would add a representational claim and decision work that the present use does not require. They keep the explanation, correction and learning routes from CB.1/5. A later proposal for a joint service would create a new, bounded governance question.
