It would be great to have to same abilities to layout light gage metal studs or wood studs as what you have with the concrete rebar tools including extensions to frame out around openings in walls and corners etc. A significant advantage to this verses using columns or custom families would be the file size. It does not appear to me that the rebar add very much to the file size or slows the graphics down too much so a similar component for studs I hope would impact the file and speed in the same manner.
