I can't imagine why. But, I always learn something about how some ICAO states apply PANS-OPS.
PANS-OPS contains specific guidance material relating to the early termination of the precision segment with a missed approach turn at a designated Turning Point - not a MAPt as as such, but effectively so.
If you are a Cat B aircraft and do the ILS you have a minimum of 600ft but if you turn the gp off you get down to 580ft
Strange yes, but also remeber 600ft = DA 580ft = MDA
