Similarly, each area has a boss who is a major character: Toriel is the boss of the Ruins, Papyrus is the boss of Snowdin, Undyne is the boss of Waterfall, Asgore, Flowey, and Sans are the bosses of New Home. Muffet is not a major character, and thus does not fit that theme, whereas Mettaton is and does.

The claim that there are different monsters in different areas doesn't prove anything, since in most of the areas there are specific screens where particular enemies can be encountered: Temmie can only be encountered in the screen leading up to Temmie Village, Loox and Vegetoid can only be encountered in certain rooms in the Ruins, and so on. You presumably would not take these enemy placements as indications that the various areas are broken down into unique areas, but by the same logic enemy placement in and of itself cannot be the indicator of a unique area.

Being able to call Undyne and Papyrus isn't an indicator of a new area, as by that logic Snowdin through Hotland would all be one area, and the CORE and New Home would constitute another.

You're free to treat Hotland and the CORE as different areas within your own mind. But for the purposes of the game's mechanics, they are both treated as the same area, and thus are treated that way in the Wikia.
