In my opinion, giving partial information in the man page is the worst case scenario. Seeing as it already includes a good number of the available commands, there is significant potential for users to assume that the list is comprehensive. If the owners want to rely explicitly on info pages, they should strip the command list out of the man page entirely and simply leave a note saying "see the info page." Until then, I think leaving holes in the man page is a disservice to users.
