I doubt Relic would care about Modding Support. Look at what's happened to CoH2 Modding - They tried promising a full modding experience, but then left the Mod Tools to be bare bones.
CoH1 Modding - The tools were community-created. All important features were implemented - The ability to change Sounds/SFX, 3D Models, Textures, VFX, etc. That's how we got Modern Combat.
CoH2 Modding has none of those important features. I would guess that it's either they just don't have enough time to commit to delivering the Tools properly, or they just don't like Modding in general.
Just look at that CoH 2 Star Wars mod. Technically the units are based on Star Wars designs (Clone Troopers, Storm Troopers, etc), but the Mod itself automatically suffers because it's limited (stuck) to using the game's in-game Vanilla WW2 Models, and especially VFXs, because VFX is important when it's supposed to be a Sci-Fi content with lasers shooting everywhere.
If Relic really cared, we wouldn't be waiting for a full Mod Tools for years.
