Personally if they could've had an Apple accessory that mitigated that (ie, something built-in like Griffin's breaksafe - maybe recess the port so the accessory could be flush), it would've been a coup.
Everyone needs to plug in their laptop; Not every one needs 4 connectivity ports.
I'm a MagSafe fan myself. I remember pre-MagSafe laptops taking a flyer now and again, and being the worse for it.
That said, I can understand why they did it. Laptops are lighter now, so the corresponding damage may be less as well. And I don't know how snugly the TB3 ports fit. Maybe they disconnect more easily than, say, Firewire 400.
I've got a couple of years left in my current laptop. I'm hoping there's a solution that incorporates some type of break-away power connector.
