Wayfinder enhancements

(Also asked on the facebook Pathfinder Society group, but I figure more opinions never hurts...)

On Wayfinder enhancements:

The Inherited wayfinder enhancement (Pathfinder Society Primer 29) reads: "When purchasing a wayfinder enhancement that would normally replace the wayfinder’s ability to cast light with the ability to cast a different spell, the wayfinder retains the ability to cast light, allowing it to cast two different 0-level spells."

My question: is 'light' required? For example, could you have an Inherited Discerning Jade Wayfinder, and have it casting Detect Magic and Guidance instead? Or even an Inherited Discerning Dayfinder? (The dayfinder modifies the light capability instead of replacing it.)

I believe light would need to be one of the two because that is what the item is originally designed to provide.

To answer the principal question, I'd say yes, light is required. As you correctly quoted, "the wayfinder retains the ability to cast light." Note that they published light in italics, which indicates that exact spell, not something akin to it or a general concept of shedding illumination. And it must be retained, per the text.
