Diminutives aren't necessarily "forms" though. Category:Dutch diminutive nouns also contains nouns that have no non-diminutive base form. The reason that it's done either-or is that most nouns have a diminutive, so if you categorised the diminutives in Category:Dutch nouns then that category would end up containing alternating pairs of nouns and their diminutive. That would make the category less useful overall. And there are in fact several ways to form diminutives in Dutch, but one of them is more or less universal.

And I agree that those categories are useless too. For Spanish even moreso because the "first person form" can be any of a number of forms, it's not just one form. I don't see that as a justification for more useless categories though, that's just a straw man argument.

I noticed that you mentioned this is also a derivational relationship. That changes things quite a bit. I have less of a problem with a category that lists imperfective verbs that were derived from their perfective counterpart. That's much more objective and less arbitrary, because it focuses on etymology and not on some random collection of requirements. Maybe Category:Serbo-Croatian secondary imperfective verbs is a better choice for a category?
