If memory serves correctly they were all inhibited well before the upgrade to GR4, at which point the published Mach limit came down to 1.3M. Saved a lot of maintenance effort that had been wasted on hydraulic leaks and rigging of ramps that the GR variant barely ever needed; addition of the laser rangefinder had scuppered higher Mach numbers anyway.
