Currently even if a patient is public matching algorithm seem to ignore features which are explicitly specified as "not observed", e.g. the JSON returned and the "show phenotype and genotype similarity" button on the patient page do not show any non-observed features.
Even if those features are not useful for the matching algorithm itself, saying that the matched patient has those features may be useful, especially if the "source" patient has those "not observed" features as well.
