Robert, I believe your explanation is correct.

It could probably be mentioned in the footprint somewhere that
interdependencies of protocol changes are often complex, and some times
the changes themselves become complex as a result.

To combat that, minimizing cognitive load and complexities helps. As a
guide line:

    nothing left to add, but when there is nothing left to take away."

I believe the thinking such as behind this particular change in Large
[1] is a good example of this in action, and encouraging to see.

Best,
Martin
