public boolean getIgnoreUnsupportedTraits() {
        return ignoreUnsupportedTraits;
    }
Specifies what to do when the {@code }httpPrefixHeaders} trait is
found in a model.

<p>OpenAPI does not support httpPrefixHeaders. By default, the
conversion will fail when this trait is encountered, but this
behavior can be customized. By default, the conversion fails when
prefix headers are encountered.
