Good riddance!

In my experience MagSafe 2 ruined the MagSafe connector design. It’s nearly impossible to use MagSafe 2 in anything but a stable flat position. Forget using it while laying down.

Also, I work in a metal fabrication workshop, which means the brass contacts and their housing on the laptop side of the MagSafe 2 connector on my MacBook Pro are now blanketed and burned from poor contact due to metal dust interfering with the connector.

There are aftermarket MagSafe type connectors for the new MacBooks. This is a superior design in my opinion because it makes both sides of the connector replaceable.
