USB-C solves the arcing problem in a similar way that CCS (EV chargers) does. It doesn't engage the high voltage pins until a low voltage pilot makes contact.
I'm not sure exactly how USB solves that for disconnecting (CCS locks the connector in) but I imagine the pilot would disconnect first and that would kill the PD pins during disconnect.

Don't imagine, just look at USB-C socket. So the answer is "not really", at least I didn't noticed pins for the power being longer

The 240W cables have a different spec so that's not indicative of what you'll see for 48v.

It seems that 48 volt USB-C might still have some issues with sparking during disconnect.
There's likely a better source but here's some discussion on the topic I found.

Increasing current on the other hand heats stuff up which... is also dangerous
