For Type 1's and probably Type2's on MDI, there is a little hope on the horizon. The ADA Standards of Care in Diabetes-2013 states that patients on MDI (this would include pumpers) need to test many times a day. A number is not stated, but times to test are described.
You can find the relevant part in Section V.C.a and it states:
"Patients on multiple-dose insulin (MDI) or insulin pump therapy should do SMBG at least prior to meals and snacks, occasionally postprandially, at bedtime, prior to exercise, when they suspect low blood glucose, after treating low blood glucose until they are normoglycemic, and prior to critical tasks such as driving."
