No, unless you put a sense resistor on every power pin, and add circuitry to individually measure current per pin.

If the alternative is starting house fires that sounds pretty reasonable.
The problem isn't whether reputable manufacturers will do it, it's whether the bottom of the barrel cheap cables from eBay/Amazon will do it.

The advantage of USB2 is that it's very hard to screw up. The design is so simple that even the cheapest cable is usualy "okay" because making an "okay" USB2 cable is so simple.

In contrast, making a USB-C cable is much more difficult, which means unscrupulous manufacturers flood the market with bad cables that fail with disastrous side-effects.

The solution would be for devices to test cables before letting them work.

If my iPhone tested the cable was up to spec before charging and said "error, bad cable" if any test failed, then china-cables would be forced to pass all the tests.

If the pin turns bad during use, you can't do much
