A PS:

There are two analogous gaps in the Applescript library:

The cache has TASK.effectiveFlagged and TASK.effectiveDateToStart

but in the absence of effectively flagged and effective start date properties, we only have applescript filters like:

flattened tasks where start date is missing value

and

flattened tasks where flagged is false

which (probably unexpectedly) include tasks which are shown by the OF GUI as effectively inheriting flagged status and/or start date.
