here is the gist of how it was explained to me : all stages is fine for adult Corgis, but for a normal Corgi pup, a 'watered' down version of puppy food (as all stages would tend to be so that it is also fit for a normal adult) is much less preferable than straight food designed for puppies. That is from New Zealand's foremost canine nutritionist and was confirmed by two premium dog food producing companies who produce both all stages designated food and speciallist life stages food.
