What it will do is get rid of the ridiculous requirement to make circuit calls on area frequency for airfields not marked on the chart.
As if anyone ever did.
I have never heard anyone broadcasting circuit or taxiing calls on the area frequency - a totally unenforceable rule which I think was roundly ignored by those who actually heard about it. The vast majority of the piloting population probably never ever got to know about this new rule anyway, certainly not Farmer Bloggs on his dirt strip in Upper Whoop-Whoop(er...no relation Capn!).
