Are there modded multiplayer games that allow mods to be downloaded directly from the host?

Question

Game development

That is, without (auto)subscription and any self-configuration for server (host) guests.
Modifications, in turn, may not be published anywhere at all.
I just don't understand why they don't do it. It would be convenient, at least as an option (i.e. a custom feature). Are there any legal restrictions? Or are there other reasons?

Download maps and mods* from host.
*starting from 3.3.0 and still have bug #4789

Answer 2

Look at Warcraft for example. That's exactly what happens there. Why didn't they do this before? Because it wastes a lot of internet. Why don't they do it now? Because it can't be broken into many small skins, dls, etc., and then sold.

Answer 3

What do you mean not published at all? At least on a host they are published.
At the gazebo, several games (skurim remastered, doom) have an internal mod store, if that's what you're talking about. Doom is quite a network shooter - there the levels for the network game are downloaded from the store inside the game.
