I'd like to propose the replacement of the list by the expanded forms (including gender and forms) available | here.
The reasons I believe it should be done:
the lists are already done in my personal page. Just need to move and replace the old ones.
the style used in the expanded lists is the updated one used on the list of pokémon, list of shinies etc
the lists include event pokémon, which are sometimes released before the standard form (like shiny stantler with bells being released before shiny stantler, or shiny wurmple with hat being released before shiny wurmple). So including the non-costumed in the list of released forms (how it is now) can be confusing.
some gender differences are really different (like Hippopotas, Frillish, Jellicent, Meowstic ...) and people want to know that for collecting purpose. I know that this info is present on the list of gender differences, but I think a list of all forms should include a form that is difference due to gender reasons
this expanded list include a | Guide to every released (and unreleased, but present in the game data) form. Its easier to check it out if one's live dex is missing something.
this lists aggregates and summarizes all forms/sprites that are scattered across the wiki: event pokémon, gender differences, form differences etc
