Nominally, yes, but there are a lot of Wonder Woman fans resistant to the idea and have been praying for DC to change their mind and back out of it. I'm open minded to it, but I've seen plenty who aren't.I thought she was back in WWII in main continuity after that story in Wonder Woman #750? And didn't that story seem as if she was an inspiration for Alan to become the Golden Age Green Lantern?
I agree it looks sloppy upon first inspection. Another theory I have is given this is a time travel story being set up with Degaton they represent specific team incarnations and characters that will show up or be visited.General symbolism is fine, and it doesn't have to be comprehensive (especially considering how loose JSA membership was getting in later years), but having duplicates in your "general symbolism" collage just seems, I dunno... sloppy?
