I agree, by the following reasons, that it's appropriate to delete the
`make-variable-buffer-local' as you proposed:

Since AUCTeX run `TeX-auto-add-type' only once per an information type,
`add-hook' in this macro should operate on the global value of

There is another instance of `add-hook' on `TeX-remove-style-hook' in
the form
(add-hook 'TeX-remove-style-hook
          (lambda () (setq LaTeX-largest-level nil)))
in latex.el at its top level. I also think that this `add-hook' should
operate on the global value of `TeX-remove-style-hook'. Thus it looks
apparently wrong to apply `make-variable-buffer-local' to it.

How do others on auctex-dev list think?

This isn't correct actually, though it isn't important under the current
context. Many files among style/*.el add their own information types by
this macro.
