The first question is whether Bitcoin needs a change for this yet. And I think that the answer is still no.

And if so, sorry, but your question makes no sense (and I'm being nice). From what I've read some of those submissions may be a bad joke. So we will need to see which of those is/are good enough and pass the test of time. May be some options, may be none(!), however, we simply don't know that now. So, again, your question doesn't make sense because it cannot get a proper answer.
