A section registered before the controller's terminal took over, or set there, is replaced or removed by a proposal the operator approves

It could not be changed at all: propose refused a name set there and never replaced one. The ask now says plainly that
it replaces or removes the registered section and binds its text's digest; on Approve every node renders the new text
in the place of the old (a removal leaves it out); a replacement keeps the section's own heading form (issue 340 note 14).
