It's not so much flipping an on/off switch as it is trying to fix an issue where the underlying issue is not readily apparent. If you've seen some of the other threads on the issue, you'll note that John has been on the record as saying they don't know why it's not working, and have to this point been unable to find the underlying cause.
Placefiles can be put together that can limit SN icons shown on GRL3, so it can be set to only show the ones you want shown, as long as they're running their SN beacon via another means.
I don't believe anyone doubts that it hasn't been a difficult process the past few years and yes the threads have been followed (I started many of them ). I'm just happy that APRS>SN has shown signs of life recently.
