The option we have now are magnetic breakaway USB-C nubs, but I've been hesitant to jump on that train because of stories about them breaking off in ports, short circuiting, or failing to connect properly. And especially if you have a 15" MBP with the 87W power brick, I don't think they can handle that amount of power.

Eventually I hope to see some well made versions of that from known good vendors, but even things like Griffin BreakSafe have crappy reviews right now.
