Sadly that slipped out the door in 1.4 with counters. It was pretty juvenile I guess, but I was writing the code, didn't want to break my stride thinking of a number, that was the first number that came into my head, I forgot about it / assumed it would get changed before release, and it never did. We can always claim it was just the next number in some internal sequence…which it sort of is (the 50s are used for riak_object binary format.) Anyway, there you go…to remove it would involve upgrade code for counters…your call. It is just a Bill And Ted reference anyway, try not to be to puritanical about it.
