Questions about expansions and game modes

I have about the original Separate Ways.

In the remake, it is a DLC/Expansion and that is easy to understand. However, there is a page for Separate Ways in the original version and this was already included in the game (although, as far as I know, not in all versions of it).

In this case, should there also be pages for Assignment Ada and the Mercenaries from Resident Evil 4? Should there be pages for the Pokémon Stadium's Kids Club? For the Motor Kombat from Mortal Kombat: Armageddon?
