Does Freedoom needs extra multiplayer monsters?

From the wiki:

Beginning with Doom II, most stock levels also contain extra monsters, usually boss monsters; these provide more fearsome opposition for cooperative play and act as booby traps in deathmatch play. (Because of the extra monsters, some speedrunners enjoy the challenge of completing max runs in multiplayer mode, using DOS utility programs to create a fake "second player" who neither moves nor attacks.)

Or I just missed them?

Freedoom could use multiplayer-only monsters in the maps, for the balancing the difficulty/progression on coop/dm.

phase 1 complete devoid of this feature in multiplayer i'm sure, dont dont sounds a bad idea.
