In https://golang.org/cl/160998, RSA-PSS was disabled for (most of) TLS 1.2. One place where we can't disable it is in a Client Hello which offers both TLS 1.2 and 1.3: RSA-PSS is required by TLS 1.3, so to offer TLS 1.3 we need to offer RSA-PSS, even if the server might select TLS 1.2. The good news is that we want to disable RSA-PSS mostly when we are the signing side, as that's where broken crypto.Signer implementations will bite us. So we can announce RSA-PSS in the Client Hello, tolerate the server picking TLS 1.2 and RSA-PSS for their signatures, but still not do RSA-PSS on our side if asked to provide a client certificate. Client-TLSv12-ClientCert-RSA-PSS-Disabled changed because it was indeed actually using RSA-PSS.
