IMO, CHECKLOCKTIMEVERIFY should be included in that list, too. RE soft fork vs. hard fork: It's about this time at Mike Hearn will chime in, on the side of hard forks. Hard forks are in a sense much cleaner, and permit solving problems not otherwise solvable with a hard fork. However, hard forks clearly have risks, notably the Big Risk akin to a US Constitutional Convention: once you open the door, anything can happen, any rule no matter how "sacred" can be changed.
Soft forks are not without their own risks, e.g. reducing some things to SPV levels of security. Leaning towards soft fork, but it is a good discussion to have. A poorly implemented soft fork may potentially require a hard fork to fix rollout bugs.
