I have no idea as I am not a software programmer. I was simply speculating, but I suspect it could be due to the fact that (a) the module would affect other types of returns (perhaps adversely) and, (b) the module would not be necessary for at least one type of return.
Most returns of this type that have a substantial number of transactions are printed and mailed (or a summary is used and then, for example, the 1099-B is printed and mailed along with a transmittal form).
