One of the value props was the inability to reset and resell if it were lost or stolen. Now that it’s cracked there is more of an incentive to not try and find the owner.
As for actual data security you are probably right

It's sure one of those nice to have features, but there's no good reason why it has to be mandatory like it is. All in all, having a device purposefully retain some information when you factory reset it is user-hostile.
The "lost or stolen" argument also hardly holds for desktop computers like Mac Pro or Mac Mini or iMac, yet they still have T2s in them.
Why ? People's houses get broken into all the time.
And probably 99.999% of laptops never leave a person's house.
From what I could find, the encryption keys of the T2 are still secure but the OS running on it is not. Wiping the SSD and/or repairing another might be enough to resell the device without any locks but I'm not 100% sure about that.
> ..Using the checkm8 exploit originally made for iPhones, the checkra1n exploit was developed to build a semi-tethered exploit for the T2 security chip, exploiting a flaw. This could be used to e.g. circumvent activation lock, allowing stolen iPhones or macOS devices to be reset and sold on the black market.
