Phishing is only a subset of the issue, so I don't think that name's appropriate, besides being used for other things in other contexts (which would be another reason for me not to try and overload it).
I'm not saying we need to overload phasing, but rather to not treat the trifecta like a regular security vulnerability. As defined originally, the trifecta is analogous to phishing, but of course it's only a small subset of the issue.
