'custom-add-repeat-choice' can help to add more choices to the
customizable variable 'context-menu-functions', so it would be
easier for users to add a function from the package that the user
is really using.

The main customization point is

  'M-x customize-variable RET context-menu-functions'

that will provide more choices with the help of
'custom-add-repeat-choice'.
