Xiph.org has released Theora 1.1 alpha 1. This is the first release to include the rewritten and much improved "Thusnelda" encoder. See Xiph's press release for details; this mailing list post links to binaries.

I think the point was to advocate PSNR for comparing different version of the exact same codec on the same content, but not for comparing across different codecs or content (and even then be careful not to rely on it exclusively). The updated appendix discusses some additional context you would need to understand this, since it's rebutting a paper that wasn't otherwise mentioned in the original discussion.
