I've heard rumours that may be a leftover from a crafting system they worked on earlier in development. It makes sense to me, at least, that that would be meant to teach you to gather things to craft some upgrades, such as the spine quest for the drifter's cloak.

All that to say, agreed, and I don't assume they'll be adding more wishes like that, most wishes weren't lame "collect X of Y" chores, and I highly doubt Team Cherry would believe those to be the best parts of Silksong.
