The different behavior from v4 looks like is caused by the introduction of Groups in v5, there is some processing that happens to support groups which as a side effect triggers a final update even if there was a previous update.

I guess it's a bug since the final update for processing groups shouldn't need to be done if there are not any groups being transformed.

It's not a particularly harmful bug though, it may run the risk of messing up group handling to fiddle with it.

Support for groups involved some pretty big changes throughout the system.
