I know it has been run before.
As I write this there are:
54,751 dicot taxa with no TFR defined
11,475 monocot taxa with no TFR defined
Many of these are legitimate taxa which have alignment to POWO which have been created since the last run of the automated creation.
Cleaning these out would allow curators to at least more focus on the taxa records that do not align to POWO.
