Only accessible via C and useless aren't the same thing. But sure, add it.
I'm still on a -1 for that. You mentioned that there is perhaps no reason to delay a decision on this matter, but IMO there is no reason to rush either in doing something we may regret. And I am not the only one on this thread expressing concern about this extra data thingy.
If this extra data field is going to be used to identify from which node a commit comes from, then it is another feature than what is written on the subject of this thread. In this case let's discuss it in the thread dedicated to replication identifiers, or come up with an extra patch once the feature for commit timestamps is done.
