No, she is headlining two animated shows as Batgirl. DC Super Hero Girls based around their merch line, and the Lauren Faust Superhero Girls show. Batgirl is front and center in both of them.
Cass was long gone from being involved in the Batman books before the New 52 happened. She was sidelined once Steph was the new Batgirl, so blame Steph for the minority character being sidelined if you want, but I said in a previous post that if you are upset about Steph and Cass not being Batigrl anymore then that is understandable but also a completely different argument.
So Barbara should strive to be like Alfred instead of her own superhero? Alfred tends to get written like crap or abused in his supporting role in Batman. He isn't treated very well despite being a fan favorite.
If they were going to make Barbara a hero again then there is nothing the Oracle identity offers that the Batgirl identity doesn't offer more of. It is a bigger identity and a more marquee name. The same reason people want Steph or Cass back as Batgirl is the reason why some fans want Babs as Batgirl. It is an identity that offers its own solo series and many more opportunities for exposure.
Again, being upset about Cass and Steph because of Barbara as Batgirl again is a completely different argument and something you can't argue against, since it is a basic liking one character more than the other, but only on the Barbara side there is no way she got worse off than someone like Dick. Dick got demoted as Batman and his experience as Batman was made redundant, he lost all of his Titans history, all his history with and in the JL was made redundant or erased, and the only DCU characters he knew or could interact with were Damian a bit and Barbara. Going from were he was to just Nightwing was a massive step back. First time in decades he only appeared in one book. Across all fronts it was a step back for the character.
Barbara went from her role as Oracle to having her first ever solo book which is a step up in terms of awareness. So while you might not have liked the change it was a step up in terms of opportunity and exposure. So she went from a supporting character to a hero leading her own title for the first time in her character's history.
