I think it is on the roadmap to integrate Geometry Nodes into the BlenderBIM addon, but I also feel like it will be a lot of groundwork before it just works. I don't see why the generated meshes wouldn't be usable to create the 2D drawings, after all Geometry Nodes uses the same base mesh types as vanilla Blender : Meshes, curves, etc.
However the part that is a bit trickier IMO is to roundtrip the data and make it display correctly in other softwares. Also, Geometry Nodes can aggregate complex meshes into a single object and operate efficiently because of that, werehas the IFC schema tends to explode complex constructs into several atomized objects, which is a different paradigm but not unsolvable.
