I do not think changing it would be in the scope of this series.

It makes sense to document (1) that zero is success, non-zero is
failure, to help those who are reading the current callers and
adding new callers, and (2) that we are aware that the exact
"non-zero" value chosen for these are not in line with the rest of
the system.  The latter can just be a "NEEDSWORK" comment.
