You presume that there was a reason to bring the NEPA process to a completion. Such actions can be withdrawn when there is no longer any party proposing to implement an action requiring a NEPA process.
I would agree if they didn't actually do anything. What they did was implement Alternative 5 of the Environmental Assessment. That alternative (wag bags) had potential impacts identified. It's not normal to implement any alternative in any EA without completing the process.
The idea of NEPA is to engage the public in the decision making. That didn't seem to happen.
