Deletion of List of allergies (2nd nomination)

Comment: The claims that the list is impossible to improve are obviously false.  For example, a quick search immediately shows that the WHO maintains a classification system for allergens.  Here is http://www.allergen.org/viewallergen.php?aid=319 their entry for the common allergen Fel d 1 which occurs in cat saliva.  There doesn't seem to be any reason that we couldn't improve the list to incorporate information of this kind and it is our |editing policy to make such improvements rather than deleting
