I would think this could then cause a problem. Hugin tries to take advantage of the specific optics to make adjustments so that you can get a good stiching. If you count on software to automatically do the adjustment, and it is just basing it on interpreted geometry, Hugin will only be able to guess on how to make the adjustment.
This may not be a big deal when you are dealing with panoramas coming from less extreme focal lengths, but if you start getting at very wide angle or fisheye shots, then you could have issues.
Now, Hugin is pretty good, and it may be able to overcome the issue anyway, but I generally eliminate any middle processing as much as possible with regard to lens corrections because I want to let the software that is built for stitching do what it needs to do.
