actually minigames server is designed for mini-games.
mini-game means not a full game, but can refresh you from the actual game.
and these mini-games include various game modes.
so actually every map in minigames server can be called a minigame map.
For parkour/escape maps, i agree. But for deathrun, it's overplayed. that's the reason why people out there make deathrun servers,
and basically deathrun maps are called dr. Maybe deathrun is a bit different?
anyway there are some people in minigames server who love parkour, multigame, deathrun, shooting maps, and the other maps.

Note : In a nice multigame map, there could be a climb, slide, deathrun, surf, race, some gun-based maps, and possibly some other maps(item battle, balance, boxing ring, etc.).
