I do not know whether this idea has yet been brought up, thus I'd like to leave my two cents behind. I would recommend the dev team to use git submodules instead such that it's easy to update mods in bulk. The flipside being that it'll no longer be a simple git clone of the entire repository.

sbz already uses submodules for some mods

to further clarify, unified_inventory used in this game is heavily modified. so it does not really benefit much from making the mod a git submodule.
