More like dimminishing navigation skills are not a good idea.
geomagnetic disturbances should not affect INS navigation so airliners would not be affected. My concern is that keeping a dead reckoning plot on the enroute chart prepared by operations used to be manditory! Not so much any more.
If that is really the case, that is a concern.
