Currently, users under GNOME set Xft.dpi to be 96.0. Otherwise, the default DPI comes from the X server, which often sets the DPI based on the monitor size reported by DDC. These are often incorrect. I would like to see more systems standardize on a default DPI of 96. It would help usability of Linux systems a lot, and improve default font selection. Ideally, the default config files from fontconfig would include a setting for Xft.dpi to 96. See http://scanline.ca/dpi/ for more discussion.
Fontconfig shouldn't be in the business of picking DPI for default usage; consider the case of using fontconfig to generate printer output. This could be an Xft change though.
So I guess this invalidates my suggestion that distributions add it in their local.conf files. Changing it in Xft would mean just having it default in code, or is there a standard place for x resources to be defined?
