Of course, I was mistaken.  SRFI 133 just made 43 consistent with R7.

Indeed, SRFI 43 vector-map, with its two-argument mapped procedure, is
indeed an odd case among the many "map" functions of Scheme.  While
having access to the index is useful, the R7/SRFI 133 versions are
more consistent.

Exactly.
