It seems like those should be two separate things instead of lumped all
together in a monolithic "You can do this if you want... or whatever!"
"Snapping" is definitely something different than antialiasing. It's a
huge pain for anyone trying to provide a(n accurate) simple 2D primitive
library.

I want to "adjust line positions and line widths to align edges with device
pixels" but not "the user agent might turn off anti-aliasing for all lines
and curves"

yeah, at first blush that seemed what was needed.
However, this simply turns off antialiasing completely so regular
artwork looks terrible.
That's a quality of implementation issue. The description of the property
value says,
"Indicates that the user agent shall attempt to emphasize the contrast
between clean edges of artwork over rendering speed and geometric
precision. To achieve crisp edges, the user agent might turn off
anti-aliasing for all lines and curves or possibly just for straight lines
which are close to vertical or horizontal. Also, the user agent might
adjust line positions and line widths to align edges with device pixels."
I'm not sure what use case you have in mind though. Perhaps it's something
that doesn't fit that description?
