I have noticed this as well, especially when I served on our local bike/ped advisory board. The board always discounted the importance of pedestrian facilities because no one came to advocate for them...because no one considered it a "special interest."

I also wonder if it's because we assume accommodating walking is simple, but it's more complicated than just building sidewalks -- you have to also get the built environments and land uses right. And maybe most mobility advocacy groups don't see that as part of their bag.
