I would assume that, much like icons, a framework should typically
prefer the smallest image that does not need to be scaled up.
e.g. with icons:
34x34 - 128x128 is scaled down
33x33 - 128x128 is scaled down
32x32 - use the 32x32 native version
31x31 - 32x32 is scaled down
30x30 - 32x32 is scaled down
Is this an observation of current behavior in Cocoa or a wishlist? If
it's the former, I'd like to know how you achieved it. My experience
with NSImage is that at 31x31, 128x128 is scaled down rather than
32x32, which makes for a suboptimal appearance.
It's actually an observation of the Finder's behavior. I do not know
what APIs the Finder uses internally to get this behavior.
Upon experimentation I find that the Dock does not work this way,
unfortunately.
This is actually the documented behavior:
"Although the Dock doesn’t use hints (it uses a sophisticated
algorithm on the 128 x 128 version), [smaller-sized] hints are
important for preserving crucial details in Finder icons."

Wow, that's really bizarre. "Hints are important for preserving crucial
details, but the Dock doesn't use them because it's scaling algorithm is
so super-sophisticated." I call BS. ;) The Dock should respect the
smaller sizes.
