Adobe Illustrator Support in DAM

I am currently looking to see if the built-in DAM in Pimcore could be of use because we are using the PIM and are needing something to control all of our assets. One requirement we have is the support for .ai files. With the current DAM in v6 .ai files are recognized as images however the thumbnail and other image processing features are broken. On there is a marketing image that clearly shows ai file support.

Looking through the documentation I noticed that in version 5 Adobe Creative SDK was used but in version 6 they moved to use miniPaint Image editor. My question is did Pimcore ever support ai files and if so do they ever intended to support it again if the feature was removed? Also is there any extenstion currently that can give us basic DAM functionality on ai files like other image files have?
