I agree.  I also suggest to amend the documentation to make this issue
more explicitly mentioned.  The ELisp manual already says

 -- Variable: format-alist
     This list contains one format definition for each defined file
     format.            ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
     ^^^^^^

"Only one format definition per format."  But I think it won't do any
harm to specifically warn about violating that.

Thanks.
