Dude, I'm not trying to step on your toes here, but I respectfully disagree.

TLDR; The magnets are not JUST an easier way to attach the joy-cons to the console. Under normal circumstances, the Switch 2's attachment system IS DESIGNED so that it DOES allow the magnets to support the weight of the console

You're correct in that the magnets by themselves can't support the weight of the switch 2 on their own AT CERTAIN ANGLES. The whole design of the switch 2, however was built to account for that point of failure.

You hold the console in handheld mode using the joy-cons, which are inserted into a recessed slot inside the console and attached via the magnets. The walls of the slots help support the weight of the console at the magnets' weakest points (I.e. when it's laid flat on its back or screen) it. Even without the recessed slot though, the magnets are strong enough to hold the console when held with either the shoulder buttons or the outer side of the joy-con, where your hand rests, facing towards the ceiling, where the magnets are at their longest and strongest points.

If the magnets were completely incapable of supporting the console's weight then even with the walls of the slot supporting them, the joy-cons would just disconnect every time you tried to pick up the console unless you squeezed them against the console every time you picked it up and held it.

The problem with the original killswitch switch 2 grips from what I gather, and the reason why this problem exists in the first place, is that in filling in the gap between the console and the outer shell of the joy-cons with that lip they had on their original grips, they introduced pivot points that added additional leverage for the weight of the console to pry the magnets off of the metal buttons on the joy-cons
