This is an issue where there just weren't sane defaults.

Some people will want power to be turned off at the slightest increase in price.

Most people will tolerate a small increase in spot pricing over the normal state of affairs, but would like to be disconnected if, say, electricity more than doubles over what would be normal for that time of day.

Other people will tolerate huge increases in price-- and should be able to opt into this behavior after careful acceptance of disclosures.

Indeed, having different thresholds where demand goes away is essential for spot markets to work. Otherwise, the only change in demand is from those actively watching the spot rates (either through automation or manually). It makes sense to provide a minimal level of that automation "built into" the product.
