This regression I've personally tested and confirm:
You can't hit anywhere near "line rate" with usb 3.1/3.2, though an Intel Mac will gladly do so with the same _exact_ drive. You will experience write stalls and other performance problems. I don't have a usb4 drive to test by I wouldn't hold your breath.
I do not have a Thunderbolt 3 device to test. Google tells me it's a problem: https://9to5mac.com/2022/04/18/m1-mac-thunderbolt-4-ports-sp...
Expect _at most_half the advertised speeds and feel lucky if you achieve them.
EDIT:
From the article I linked: I just noticed they suggest try connecting my drive to a Thunderbolt 3 dock first. LOL, ok, I'll give this a try.
