This. As with Hawkeye the MCU has been the only place that Wanda's friends interact with her. Want to see her interact with her fellow Avengers? MCU is your only venue for that.
In 616 Wanda barely interacts with her old team mates and has had pretty much zero interaction with the likes of Kamala or femThor. In 616 she only has Steve, Stephen, and Agatha, with the occasional Billy cameo, while Pietro has had a bust-up with her.
That Emerald Warlock line about her lacking an arch-enemy makes me want to slap Robinson. Chthon is her arch-enemy (and yet also ally/benefactor), and Wanda has perhaps the strongest rogue's gallery of any Marvel female.
I do have this hope that Chthon will try to corrupt her in the fight against Thanos as that would make that an even more tense struggle and the moment where she shows how strong she is.
