Many racks and lowriders are also adjustable for different fork configurations. Tubus racks are the easiest example, but Surly and Blackburn also sell racks. You must like this fork to pay to alter it.
Thanks for the feedback; I figured front low-rider racks are fairly flexible and/or standardized, but it's good to have confirmation.
I wanted a low-trail bike for riding with front loads - mainly a handlebar bag, but also at times with low-rider panniers. This is already fairly low-trail (and the framebuilder might increase the rake/offset just a bit), and the frame fits me very well and hasn't seen many miles despite its age. It's harder to find 1" threaded forks to fit this frame. (I'm getting some modifications on the frame as well, and weighed doing this vs buying a new frame/fork, and decided to go this route)
Here's a picture of the frame in its pre-modified incarnation.

Good point; when I put the low-riders on I'll have front load that will probably more than offset any increase in stiffness of the fork blades.
