I'm not so much put off by DT's codename situation, anymore. I'm asking what good is all of her strutting and branding, if she's hardly in the WW comic doesn't seem to have much of anything, like an active relationship with a major character (any of them) to invite writers to plug her into more WW stories.
Forget the Siggy-Donna thing. Maybe, Steve Trevor's family could be retconned in as the family, who adopted her, when she first came to Man’s World - a variation on Dru's cover from the 70s TV show.
Just think she needs a stronger narrative tie to what's going in WW.
