Not as far as the Community knows or has been told.
It’s pretty obvious that SHM exists as a Trojan Horse to sell add-on subscription features (Scout monitoring, and soon neighbor alerts, etc.). As this is unique ongoing revenue generating features, SmartThings is keeping SHM closed on purpose… at least for the time being. This may change if the revenue products aren’t successful.
I think we expect these types of restrictions on the platform to increase from time to time. SmartThings has to earn money somehow.
