If you start thinking custom, if you plan to go with disc brakes, having cantilever posts on the fork could come in handy if you ever want to put a small rack on the front.
Note in the photo that I have a Tubus Ergo front rack for pannier mounting and I also have a small platform rack. I do not put much on that small rack, but it is handy to have. In first photo, I just have an orange polartec vest strapped on, in the second photo a spare water bottle.
