If you assume that craig/nchain is in control, then just read his twitter feed to learn that they want to recover stale coins, remove P2SH, remove anonymity as a concept.. (cont)
how removing anonymity?
P2SH wasn't part of the original, so it makes sense. All the other things don't make sense at all.
How has not been specified. Just a clarification that they want pseudonymity only because anonymity enables lawbreaking and they want to build to cater to current law.
