No, I conceded that if a feature goes away and nobody notices, you don't have to take a position on it. It's still a regression, but nobody really cares, and you can argue that in the grand scheme of things, no significant feature has fallen off the feature list.
I also noted that if a feature goes away because it is obsolete - to take an ancient example that once applied to some desktop systems, you don't have to allocate memory manually to a process because the system now does that for you - you can ignore the regression because nothing that anyone was doing before that they can no longer do now (say, allocate a process size of N) is anything they still need to be able to do (because the system will give the process N if it asks for it). Since there is no longer any benefit in even being able to do those obsolete things, there's no general functional regression (you can still run that process).
None of this has anything to do with whether I "like the changes". The issue I have is the way that people deny the experiences of the users by playing games with definitions of what the system was and is, as if the users were supposed to care more about the brand gymnastics than the features actually being delivered.
