There have been a couple of papers on block chain analysis that have heavily influenced my thinking and raised the priority of removing t-addresses; in particular one by George Kappos, Haaroon Yousaf, Mary Maller, and Sarah Meiklejohn. I don’t think there’s any significant disagreement within ECC at this point that they need to be removed. The obstacles to removing them are described in one of my previous forum posts. Since then we’ve made some progress on designing shielded multisig, but otherwise the issues are roughly the same.
