So true, Ignition Override
About ten years ago, decided enough was enough, especially while training new First Officers, who generally get behind the aircraft anyway, at times.
ATC askes,
Can you maintain high speed?....Negative, unable.
Can you accept a visual? Negative, unable.
Can you accept a short approach?...Negative, unable.
Period.
ATC got the message loud and clear, and the company didn't complain either.
Better safe than sorry, IMO.
