The new proposed API in this patchset never gained traction. However, if userspace decides to, it's still possible to stall if validation of setup or data fails. Because there is no real reason to hold data stage in a control OUT transaction, this patch delivers both setup and data event at once. Another reason is that delivering setup earlier causes races.
