If you have one of the expensive "supports everything" cables (100w charging, Thunderbolt 3 @ 40mbps) then yeah, the same cable will work. I couldn't even find a 10' one on Amazon with a cursory look. Some of the 6' ones were in excess of $70.
Both 100w charging and high speed data transfer are problems that get harder over long distances, and trying to do them both in the same cable requires many non-trivial feats of engineering, quality materials, and manufacturing.
No one ever said USBC was going to bring these features to cheap $5 cables you buy in the checkout at the corner bodega.
But the EXISTENCE of those $5 cables with extremely limited capability muddle the entire market. I'd call them counterfeits, except for some reason they're spec compliant!
