Hi Alan,

Thanks for taking the time to look at this.

The way I see it, this is analogous to the existing ns-antialias-text flag,
which is another rendering preference that can be changed system-wide, yet
is available within Emacs.
I would say that the use of these options is sometimes beneficial, based on
one's choice of fonts.
For example, if you use a bitmap font in Emacs, you would likely disable
anti-aliasing, but you wouldn't necessarily do it system-wide.

(I don't really know how to turn on thin smoothing system-wide, but that's
not the main argument)

As for Dr. Stallman's question: fortunately this is not necessary in
GNU/Linux, but on macOS with a non-HiDPI display I personally find the
difference significant.
