This tuning parameter toggles the automatic deletion of unused point sources. By default, it is hidden and the automatic deletion is disabled.
Point sources are used mainly for PI Interfaces, which are slowly being replaced with PI Connectors and PI Adapters, where point sources are less important. Therefore, it is also less important to keep this rather useful tuning parameter hidden. In the worst case, a user enables the automatic deletion of unused point sources and loses unused point sources that they still wanted, even though point sources are not that important anymore.
Please make PointDb_RemoveEmptySource visible by default so that it is easier for administrators to discover it and enjoy its benefits.
