I don't believe this is accurate. There is an extended certificate format which OpenSSL will accept which allows you to indicate specific trust or *dis*trust of a given certificate for specific purposes. You could, I think, use this format to produce a certificate file which basically says "I distrust this CA certificate for all purposes". I wrote a bit about this at https://www.happyassassin.net/2015/01/16/openssl-trust-and-purpose/ .
