Adobe Illustrator files (.ai) are PDF compatible files, so you can view them with a PDF reader like preview. The file still contains all the data to be edited in AI. I guess it means that PDF format is already designed to hold extra data that can be used for editing. But since pdf has many use cases, I don’t think that it will change much for editing. You still need a tool compatible with the original editor. However it will be interesting if docx like ai files could be displayed in a pdf viewer, it will save a lot of time dedicated to export/save as pdf.
