With all due respect, allow me to offer a different perspective. When you want to understand the actions of individuals inside an institution, start by reflecting upon their incentive structure.
You have a bunch of folks on a committee whose primary task is to send out patches and certificates to people who attest to having hiked certain mountains in certain time periods. Committee members literally have to check calendars for winter patches, for example. The people who do this take satisfaction from it.
Then one day someone tells them that they have a new task: determine how many "mountains" there are for the main patch. It's no small task! If the members add mountains, there are implications for environmental impacts, parking, and so forth. They grandfather existing patch holders in.
No imagine those folks have to ask themselves if they should take a mountain away!
What rewards do they get for doing so? What costs?
Who will say to them, "Thank you for taking two mountains off this list!" Now imagine, who would be furious at them?
So someone, somewhere, on the 48 Committee or elsewhere, is now tasked with a decision: either drop two mountains and now have "The New Hampshire 46," or keep the status quo ante and recognize that until this point, we got on with our hiking lives just fine in our ignorance.
I just don't see a lot of incentive to take the two off the list.
