The problem for fans who want Wanda to have a positive relationship with him as you seem to is they so set up her identity as being the heroine who overcame the person who convinced her to join the Brotherhood that writers not too long after the retcon comes down are going to default to that.
For Lorna its a separate issue of developing a framework for their relationship that is easily accessible and understandable to the audience. Wanda has that pretty solidified and on some level its important even though it limits storytelling. I think Hickman may be on a positive track there, though time will tell. Bunn sort of wanted to develop her as his generic hero daughter who has trouble connecting to him other then general father/daughter stuff. For me it didn't work too well as it ignored too much of their history. I think them being able to connect on mutant issues like Genosha you talked about, but not on other matters is the sweet spot.
