In the context of this thread, I disagree. The problem with pushing a limit is that it increases your decompression stress and risk of DCS, especially with multiple days of diving, even if the magic bracelet says that you are safe. That is the take home message, and it holds for air or nitrox, as mentioned upthread. It should be stressed that the NDL line is a bright line through a grey area - that is, a somewhat arbitrary approximation of safe N2 loading which will keep the vast majority of people from getting bent. But it's no guarantee.
On the other hand, to address the "sheep" issue, the way that you communicate to recreational divers about what lies beyond that line is to tell them that they shouldn't plan on doing it without training, and appropriate redundancy and gas reserves. But you should also tell them that if for whatever reason they find themselves with a deco obligation, just follow the computer and do the deco. You don't need to do "a little bit of deco" to make that point. By suggesting de minimis cases ("what about just ONE MINUTE of deco? Can I do that?"), we normalize variance and make the next person push it a little further.
