Might have to check this one out...
I agree this isn't limited to just T'Challa, eventually other characters like Cap and Tony will have to deal directly with the X-Men and I doubt they'll come off much better. T'Challa running a kingdom gives him closer proximity to the Krakoa nation status quo which is probably why, like Franklin Richards, he'll be used more in this X-Men era than normal.
In Wild Kingdom both Hudlin and Milligan seemed to indulge in the stereotypical "fight/argue before working together" nonsense that's defined so many superhero team ups. Hudlin's run in part thrived off T'Challa going head to head with other established heroes and villains so I guess this is the natural evolution of that.
Hickman's actively seeding potential conflict between the X-Men and the rest of the MU and there's plenty of baggage and unspoken animosity to exploit with Black Panther. One would hope editorial doesn't feed into the tension while pitting fans against each other, but money doesn't lie and since everyone knows the X-Men would win it's hard to believe they won't eventually go in that direction.
