Hello Tony,

  So essentially TLS 1.3 drops support for DH/DHE ciphers on RSA keys, but willl otherwise work as expected?

Ben

There is a common thread circulating, that all support for RSA Certificates/Ciphers are dropped in TLS 1.3.

RSA certificates will continue to work in TLS 1.3+.

What will not be supported in TLS 1.3+ is RSA key transport / key encipherment (which lacks forward secrecy, among other problems). However, this is a property of how the protocol does key exchange / key agreement and has nothing to do with certificates.
