Hi.

Isn't it the opposite? Were key servers fully trusted I'd agree 
"expected behavior" would be to blindly import the server's reply.

However, the lack of trustworthiness of keyservers is precisely why
the check is relevant.

I'd consider it security hardening and not a vulnerability.


I wasn't weighing in on whether the change be considered a vulnerability
fix or a hardening feature (which are usually deemed CVE unworthy).

My objection was to the characterization as "expected behavior".
