Looks good to me.

Just the question of if we have any problems changing the serialized
format in the back branches.  I'm not sure if that's something we've
done before. I only had a quick look of git blame in the
serial/deserial functions and the only changes I really see apart from
a few cosmetic ones were a57d312a7 and 9cca11c91. Both of which just
went into master.
