Because, like it has been pointed out in the linked discussion which you obviously haven't read, all of the other alternative-form-of template categorize, when they are used on lemmas. Like diminutives, alternative spellings and so on which have both separate categories for themselves, and for their normal parts of speech. This way you make it impossible for editors to look up verbs which are not base lemmas.
