This looks to me like a comedy of analogical errors: it's not, for example, that Windows users no longer have access to admin privileges, it's just that asserting those privileges requires authentication. Similarly, it's not that sudo is the right way to do things in general, nor is it all that important that using sudo provides an affordance to people accustomed to using it elsewhere. It's that pfexec doesn't have a mechanism to require authentication for the assertion of particular levels of privilege, and it looks like a decision was made to kick the can down the road on that. You could follow the various offered analogies conclude not that access to root should be mediated by sudo because that's what people expect but that people rightly expect there to be an authentication requirement, in principle if not in fact, between them and access to those privileges. It wouldn't be a show-stopper to say that for most people's purposes, pfexec is like sudo, it's just called pfexec and has a different configuration system because the privileges have a different structure, if you need to edit the config files, read the fine man page. The problem is a decision was made, however implicitly or explicitly, not to fill in the functional gap and add authentication. Instead of agreeing that pfexec needed to be like sudo in this respect and making it that way, we just got sudo.
That continues to be the case because the determinative constraints haven't moved an inch. I don't see the point in the subsequent Talmudic arguments about references to Ubuntu, as the protracted argument doesn't add up to the inconsequence of the point.
