emacs -Q

C-h f subword-mode

You see this at the end of buffer *Help*:

key             binding
---             -------

It's not just about this appearing before the library is loaded.
Loading the library does not populate the list of keys and their
bindings.  You always get such a heading, with no keys shown.
