fundamental-mode does not have such a hook.

Do you have a use in mind for such a hook, or is the inconsistency
just bugging you?  (Not a facetious question, I'm honestly trying to
figure out if the situation is a problem or not.)

In simple.el, fundamental-mode's definition is pretty tiny:

   (defun fundamental-mode ()
     "Major mode not specialized for anything in particular.
   Other major modes are defined by comparison with this one."
     (unless delay-mode-hooks
       (run-hooks 'after-change-major-mode-hook)))

Hmm, for one thing, I'm not sure why it doesn't just say

   (delay-mode-hooks 'after-change-major-mode-hook)

instead of checking the variable delay-mode-hooks manually.  Aside
from that, it would be pretty easy to stick a run-hooks call in there,
but would it really help anyone do anything they couldn't do before?

I am not sure what to answer at the moment. I just found this inconsistency when I tried to check if a function was a major mode function. I tested to see if the hook variable existed (probably not the best way, but that is what I did).

I then remembered that there are no hook for new buffers. Are they not set up in fundamental-mode?

BTW, there are more major modes missing this hook: Info-mode, xml-mode is what I have noticed so far.
