I don't have a strong opinion, but I am concerned about #1 and #2 for the reasons given and before Axel's and Ivan's email I didn't even imagine that a new namespace would also be possible. Since it seems to be, I have no problems with that since it would make the construct a bit more future-proof. I am still less concerned about #3 than Ivan, so either #3 or #4 would work well for me.
