Note that if you use the revert you will make incompatible gnutls with other implementations with RSA PSS. If I remember well, these ciphersuites are from TLS1.3 draft21 and they changed semantics in later drafts. that's why they were disabled in 3.6.2. I think it is best to mark the test as xfail.
