You still charge through the USB-C / Thunderbolt ports (and use a USB-C to USB-C cable with the provided power brick to do so). The MagSafe plug is just for convenience (and perhaps slightly higher wattage than is normally specced for USB-C on the beefier MBPs).

Also if you happen to trip over the magsafe cord, the possibility of snapping the connector is non-existent compared to the risk of using a USB-C cable.

It's of course a possibility but the Type C connection was designed to sacrifice the cable part first, both on the "repeated insertion" metric and for cases like this.

It's more about the computer flying off a table and into a hard surface in the USC-C trip case.
