Consider this illustrative situation: A successor receives the title, yet the reason a founder trusted certain people, rejected certain markets and protected a particular standard remains undocumented. Those decisions cannot be recovered from a corporate timeline alone.
A founder is approaching succession, retirement, exit, reduced availability or a different public role. The visible request may be a book, move, announcement, licence, archive, event or venture. The real question is what becomes harder to reverse once the first commitment is made.
Authority can transfer while the founder's reasoning, relationships and standards remain inaccessible to successors.
