Should my daughter be able to feed herself?

I feel like I’ve kind of failed my daughter. She’s almost 15 months and can’t fully feed herself (with a spoon or fork). She can kind of do it, but not completely. We still spoon her food to her and I’m wondering if we’ve kind of taken that independence away from her. (Also this only refers to foods with require a spoon or fork—she grabs foods just fine.) What are some good ways to encourage her to do it herself? Just hand the utensils to her and let her go at it? 😅
