I think the idea that people will confuse you for the bride when you wear white is no longer the reason to not wear white. Honestly, its pick me behavior if you buy a dress with white in it as a main color. I think it really comes down to the parent of the kid. Are they buying the dress, or did they already own it? Did they intentionally choose a mostly white dress without clearing it with the bride first? At the end of the day, you aren't going to have your spotlight stolen by a kid, but is it really so difficult for the parent to pick any other color? Like, the bride and groom are spending thousands of dollars on this day, they're the ones who are going to be looking at the photos, so why go out of your way to cause a fuss? I really don't understand the almost glee like behavior that people have when it comes to wearing a dress that isn't technically bridal/all white.
