Illustrator does not use this method to load or activate fonts. Not to mention this only works for InDesign. So this is not a truly fail-safe method for activating fonts. Seems pretty awesome, but without any explanation, many older (Postscript Type 1) font types won’t auto-activate from the Document Fonts folder. The fonts loaded from that Document Fonts folder will appear at the top of the Type > Fonts list as “Document Fonts”. So the fonts load, whether or not you have the fonts installed locally on that machine. The idea behind the new "Document Fonts" feature is that anyone can open the INDD file and (if all the fonts used are in the Document Fonts folder) they should see ID automatically load all the fonts for use only in that document. The packaging process saves the INDD file, Links, Instructions and Document Fonts into the same parent folder (specified in Package process).
