Now, to go off on a tangent about The Trial of Magneto:
Maybe it's just me and I have different standards of proof, but none of this stuff has ever been 'confirmed' in any way.
In Wanda and Magneto's conversation during the Gala, they clearly state that they are not blood related, something that both of them acknowledge, so its not denial on the part of anyone.
And as far as The Trial of Magneto 2, Wanda and Quicksilver are still human - the Cerebro recording was from years ago when Xavier still believed they were mutants.
Of course all of this can change by the end of the story (and so can literally anything else), but as of right now, none of stuff is confirmed.
Also, I don't understand where this Polaris is not Magneto's daughter stuff is coming from. A relationship that is frayed or going through a bad phase is not foreshadowing of a retcon of said relationship.
