I do read it. And I don't agree personally.
An other than directing him towards his solo (which is fantastic by the way so far), I don't think Mag's is vital to the overall plot in UXM right now.
I thought it was going somewhere with the "Mags helping SHIELD maybe" stuff but it didn't lead anywhere exciting.
I haven't seen any reason Mags couldn't be used in New Avengers that is for sure. He consistently disappears in UXM and Scott has no idea where he is. He could easily disappear to head to Necropolis.
But this is way off topic.
