It does go that way. You continue to ignore modern stuff yet you pull decades old stuff which you purposely are cherry picking to suit your argument. Fact is that as far as Marvel is concerned Modern > Decades Old Stuff unless they say otherwise and that's only in rare exceptions.
What a character did 50 or so years ago doesn't matter or is even acknowledge for the most part in Modern times unless it fits a certain story arc than is promptly forgotten in the next story.
Fact is that in Modern times Xavier is literally the most powerful Telepath, and hasn't been refuted in modern times, and it's canonically stated that Rachel is the most powerful Telepath after him and with his death she's the most powerful. Despite Psylocke and Emma being powerful they aren't mentioned by Xavier - Rachel is.
Which says a lot as Psylocke can literally move mountains.
Than there's whole Rachel hasn't reached her full potential yet so she still has room to grow even stronger.
Uncanny Avengers also proved that Xavier is so powerful that an untrained, untested, and unskilled with TP Red Skull is literally an Omega-Level with Xavier's power and is easily crushing heroes that have strong TP resistance and training.
Exodus was also canonically, in modern times, taken out very quickly by a new Beyond Omega. Considering that Rachel is set to appear after Will is over with she wont suffer his fate and will show a greater mastery and power than when Exodus confronted the target.
You may not like it but Modern > Decades Old Content which Marvel has proven is the case time and again.
