Blender DWG importer

Hi, i´m looking why there is no DWG importer for blender, has to do with licensing? with lack of interest in the community? lack of time or priority? I suspect that it is licensing so why ask you

(I know that there are some DXF importers, but for architectural 3d work is a little messy, not productive)

thanks in advance

i think a feature really cool for arquitecture would be linking the dwg with blender, so if you update the dwg blender updates the 3d, there are few arquitecture scenes in blender, and i think is because of the lack of good merging dwg.

There arent really any good open source dwg importers yet. Some are coming along but its very hard as it is a very closed format and therefore complicated to work with.
