> abfs isNameSpaceEnabled() call seems to raise then swallow TrileanConversionExceptions during the default execution path, logging the whole stack at debug
> this is inefficient, noisy and distracting, as now there are stack traces to ignore when debugging things.
> Better: treat Trilean.UKNOWN as exactly that and react accordingly
