Thank you Brian Potter! We have a crazy policy recomendation to de-tune the ILS for an RNP approach when the runway is equiped with an ILS, why? Because of occasional GPWS glideslope alerts if the ILS is tuned! The GPWS is valid, but because some approaches are 2.8 degree (due hot weather), if it is cold and with enough barometric error you are actually low on path compared to the ILS. Better to turn the noise off than acknowledge the issues. Reminds me of "Shut up Gringo".
It goes against all instincts to deliberately hide a piece of potentially extremely valuable information, especially at night or in marginal weather.
