As you already pointed out 72dpi is nominal on MacOS, it isn't mandatory 
or absolute. Most shipping Macintosh models run up to 1200*1600 displays, 
you'll find this is around 120dpi on an AppleVision 850 monitor.

I've a very ancient Quadra 950, it runs a monitor at about 100dpi.

Baseline resolution is in reality the number of pixels you have to play 
with, not the size of those pixels, ie you can resolve something to a 
higher degree the more pixels you have. 1200*1600 seems pretty high-res 
to me.

ie a small number of pixels, not a low dpi.

Small type, in pixels per em, isn't going to look any different on a Mac 
than it does on anything else, unless someone screwed up real bad.

There's only a problem if one decides to spec type in a resolution 
dependent way, ie in pixels, and that problem would most probably be 
worse for "nominal" Windows users than "nominal" Mac users, since at 
96dpi those pixels will actually be smaller.

The W3 recommendation for specifying type sizes for style is to do so in 
a resolution independent manner, to do otherwise would be more than a 
little stupid, given the range of displays any particular implementation 
is likely to encounter.

That sounds like carefully planned design, poorly implemented execution.
