I'm not sure if there's any official policy around this, but to me it seems that lists often get a less-stringent treatment than other article types on Wikipedia.

Here's a sampling of some other interesting list articles:

- https://en.wikipedia.org/wiki/List_of_unusual_deaths

- https://en.wikipedia.org/wiki/List_of_films_considered_the_w...

- https://en.wikipedia.org/wiki/List_of_ballooning_accidents

- https://en.wikipedia.org/wiki/Lists_of_deities_by_cultural_s...

- https://en.wikipedia.org/wiki/List_of_fictional_colors

- https://en.wikipedia.org/wiki/Lists_of_bisexual_people

- https://en.wikipedia.org/wiki/List_of_road_junctions_in_the_...

- https://en.wikipedia.org/wiki/Lists_of_websites

- https://en.wikipedia.org/wiki/List_of_sports_teams_nicknamed...

- https://en.wikipedia.org/wiki/List_of_buns

- https://en.wikipedia.org/wiki/List_of_wolves

- https://en.wikipedia.org/wiki/List_of_brand_name_condiments

And the all-time best:

I, for one, am happy these exist, despite the editorialization, etc.
