Would it be possible to give more flexibility to resource-/datapacks using Forge?

Currently you basically can't add new material to the game by using datapacks and resourcepacks. ( Without overriding existing blocks, items etc.) Would it be possible to write a mod using Forge that makes all the blocks and items datadriven like it's possibly planned for future minecraft releases ( Bedrock already getting custom items and custom blocks partially next update according to the wiki ? ). That would allow people with basically no experience in programming to make new content fairly easiliy. Things I and many other people already suggested are custom blocks and items, custom block rendering (e.g. if you override existing blocks with custom models that dont fit the overriden block you get some nasty culling errors), recipes with NBT etc. I don't know how Forge interacts with data- and resourcepacks or if it does so at all?
