One problem with trying to treat an infinite line as if it was the same as a regular object is that it can't really be used for input into all the commands as regular curve objects.
For example it would not work to try and extrude an infinite line, or revolve it, etc...
There's some potential for confusion when something looks as if it is a regular object and selects and moves like one, but then when you try to actually use it in other ways the same as other objects it then suddenly stops behaving like the other objects that it appears similar to.
In a 2D only type CAD system I guess you would not have that same kind of problem.
