I wanted to highlight that this would be a very useful feature even beyond the proposed use case of helping handle download non-free software. I would love for files downloaded via a web browser or email client to be marked as having come from the Internet. (Major bonus points if a sync tool like nextcloud can keep files I generated labeled separate from ones my coworkers made) OS X web browsers do this, and when you try to open them the OS will prompt "this came from the internet, do you want to open it". It looks like its implemented with a few extended attributes. [1] Do most of our file systems have extended attributes turned on by now? Has anyone tried to implement this yet? It seems like a small library in the freedesktop.org umbrella, and a fair amount of trying to convince other projects to adopt it.
