The set-root encoding lived in chains, where it was first needed. A committee document needs the same number, and the second writing of an encoding is the one that disagrees, so it moves to the package that owns the type and both callers read it from there. The json helpers were imported under a name borrowed from somewhere else. In this tree json is ours; the library editions say which edition they are. Co-authored-by: Hanzo Dev <[email protected]>
