I bet people downvoting you don't understand physics... :-/

  Shh... it is not in good tone to directly demask shortcomings of general HN audience. Everybody here is an expert in every topic discussed and if you got downvotes it means you have deserved it. I personally own an electronics lab but whaddaiknow. On more serious note, the USB-C just barely has dimensions to deal with 5A 50V. You need thick enough cables and traces, you need clearences and you need margins. If you look at breakdown voltage for USB C connector, it is not a lot above 50V. Usually, you would want many times your working voltage. It just begs for a tiny speck of dust or condensation, manufacturing fault, bent connector, etc. to cause bad day for the owner. Now, in a properly designed device, it technically should immediately detect the situation and cut the power. But there are two catches. One, is that at that power the short might be just about right resistance for this safety to treat is as valid. Second, this assumes properly designed device. If you cheap out on silicon you use for your charger it might just not have the capability to stop it before it gets to far and melts a bunch of stuff.

    Reminds me of those lovely "molex" to SATA power connectors. And in my marginal lay persons mind they should be superior for transferring currents. And still some of them don't fare exactly well, with lower current draws...

    Does USB-IF include wire gauge / conductivity requirements in the standard ?
