By "negotiation" I mean the server's response to the startup packet. I.e. "supported"/"not supported"/"error". > I think the behavior with v2 and v3 errors should be the same.

For GSS encryption, it was my vague understanding that older servers respond with an error rather than the "not supported" indication. For TLS, though, the decision in a49fbaaf (immediate failure) seemed reasonable. Thanks, --Jacob
