My Game is Launching soon, Multiplayer server Build question

Hi, so a long time ago i thought i read something about how dedicated servers contain epic assets or code, so they aren’t allowed to be distributed to the playerbase of your game via steam. but i cant seem to find information on that anymore

is this still true? was it ever true?

i’d really like to provide my playerbase with dedicated server, for a survival game, i do not have the resources to host it myself

anyone know?
