Magneto's place in this chapter needs its own label. He becomes Xavier's successor at the school near the end of 1985, rather than serving as a regular member of this entire 1983–1986 field lineup. Folding him into the group without that distinction would skip the very thing that makes his presence so difficult.
The trial in Uncanny X-Men #200 confronts him with his past. Whatever he says he wants to become, there are people with reasons to judge him by what he has already done. The attack during the proceedings also gives him an immediate situation in which his actions matter more than a declaration about reform.
Then Xavier entrusts him with the school. For Magneto, accepting means taking responsibility for an institution associated with a different approach to mutant survival. For the people already living there, it means facing a former enemy in a role that requires a great deal of trust.
Being appointed does not settle that trust. The job has to be carried out in ordinary decisions, through disagreements, and in how he responds when something goes wrong. A powerful speech would be easier than the daily work of being responsible for young people and cooperating with adults who remember fighting him.
His work with the New Mutants deserves its own class-era spotlight, so this post stays with the change in the X-Men's wider household. The significance here is the handover itself. Xavier leaves, Magneto stays, and everyone has to find out what that arrangement means in practice. At this point in the story, the uncertainty is part of the situation, not something to tidy away with later history.
