Filler episodes may not help the plot, but they do aid in fleshing out the characters; adding development and even expanding on their home life. (Which, to me at least, is a nice thing to see.)

Also there's one edit you forgot from the Smile dub: The girls' school trip to Kyoto and Osaka was switched to an 'Asian Pacific Expo', with all the things they see and visit viewed as 'reconstructions'.
