Our team will be adding a laundry list of file types to our whitelist in the next release. Stay tuned! We did explore removing any validation on the files but doing that is more involved than it sounds so in order to close out some of these long standing requests in the short-term we're enhancing our existing functionality. I have a large list of CAD, illustration, programming and other file types and have added py and pyc to the list but if there are others in particular you are concerned with making sure we cover please get in touch.
