Manshooter would need to get paid for the work he put into the Dynamic system mod, but i think they will leave it this way, as a mod, they dont have to support it. 
I think that is one reason why they made the game "moddable" anyway, they wanted the player base to run with the game. The difficulty lies in only having the ability to mod just so far. Alot of the modders want to do things we cant do with just the tools we have now.
Campaigns, going from map to map with the same forces intact. There hasn't been an update on the Galaxy Forge Tools since 1.03 and even then i dont know if Entrenchment or Diplomacy would be editable using those tools.
I agree that Dynamic mod and Manshooter's Volumetric Damage Effects mod are almost "requirements" for the game now. It is easy to get used to all the beauty and the sheer spectacle he put into them.
