ProhibitAssigningSingleElementsToVarargsInNamedForm is enabled from 1.3 so there is no need to make FIR accepting single element passed through named arguments. In addition, we may want to report only ASSIGNING_SINGLE_ELEMENT_TO_VARARG_IN_NAMED_FORM_FUNCTION and not arg type mismatch. But FE1.0 is reporting both so I am following it. If we want to remove the redundant report, we will probably want to remove FirNamedVarargChecker and report during resolution as a cone diagnostic.
