My mistake, the HP-UX reference was for iconv(3), not iconv(1).  The source is the current issue of POSIX, Issue 8 (2024).  Indeed iconv(1) is in the SVR4 manuals but only supporting system-provided charmaps.  Additionally, while in the SVR4 manuals, I didn't spot it on first pass through SVID Issue 3 which is the SVR4-era issue.  It looks like specifying local charmap files was added to the spec in IEEE 1003.1-2004:
