That someone doesn't attempt to always and under all circumstances be kind, courteous, and professional, I just don't know what to think of such.

That I can recall, icon style has changed only once in the history of macOS. That is too much? Now with Tahoe, such is similar yet it seems the icon file format also stores variants for dark mode, and other (monochrome?).

To not follow guidelines, whether one agrees with them or not to me I think it just shows some sign of non-conformance which some users may interpret as something. When the time comes, I'd be willing to make an icon set or try.

Whether one agrees or not, perhaps all is done with purpose. For example I may not design but for sometime I have thought the flat design of macOS, iOS, iPadOS is not ideal. Looking into it, there are people concerned with accessibility issues such as under varying lighting conditions or those with visual impairment. The new Liquid Glass may not be ideal in its form so far but I see it as an attempt to address such. Whatever design change is made for something, whether it is ideal or not at the time, I see such as attempting to address some design problem.
