With this Intel Thread Director Virtualization to ensure the VM can properly manage task placement between P and E cores, the feature ended up yielding around 14% better performance than the status quo. That 14% win was with the 3DMark benchmark running on a Windows VM.
You mean, they reduce the performance impact of meltdown&spectre fixes?
You forgot to mention the glibc/syslog backdoor discovered

Was it really a backdoor?
Backdoor implies it was deliberately put there. Looking at the CVE it does not seem intentional so just an exploit.
Are the latest generation (11th onwards) of Intel CPUs still affected by any of these two vulnerabilities?
Not by them directly but by other side channel attacks.
