Indeed I'm not convinced that style files should change the value of
customizable variables.

In the patch I submitted, the amsmath and longtable environments are
appended to `LaTeX-label-alist', instead of being prepended as they
were before, so a user can add a
    ("align" . nil)
entry in `LaTeX-label-alist' and it won't be overridden by amsmath.el.
Actually, I believe the best way would be to add amsmath and longtable
environments to default `LaTeX-label-alist' in latex.el.
