I don't think your statement about mid drives is correct.

There are some (a small amount) that support throttle. For example: https://bafangusadirect.com/products/bafang-1000w-bbshd-mid-...

True. There are a few models of hardware that allow it with a special front freewheel attachment, but generally speaking mid drive bikes are 1. Vastly More expensive 2. Almost never have a throttle only mode.
