It's just an automatically-generated mode hook, like all the others, it
doesn't need to be referenced in gnus-cus.el code.

C-h v gnus-custom-mode-hook

gnus-custom-mode-hook is a variable defined in ‘gnus-cus.el’.
Its value is nil

  This variable may be risky if used as a file-local variable.

Documentation:
Hook run after entering Gnus Customize mode.
No problems result if this variable is not bound.
‘add-hook’ automatically binds it.  (This is true for all hook variables.)
