You probably wouldn't want a BOV to control boost, for a few reasons:
1) The turbine would be spinning wildly to create boost that is just vented to the air. This would mean premature bearing and turbine wear.
2) The charge air would be compressed and heated by the turbo, before the excess is vented by the BOV. The remaining charge air is low pressure, and hot - detonation time.
3) Possibly higher exhaust back pressure by putting all the exhaust through the turbo, rather than diverting it down a fat pipe to the exhaust. This would also drive engine/turbo/exhaust valve heat up.
