I've been running into the same issue for a while now. Using the Default Policy set to Subscribers for Files works well when adding files to Phriction pages and Maniphest tickets. However, when adding binary files as part of a Diff the creator of that Diff needs to change each files permissions by hand before a reviewer can download the Diff. Moreover, this needs to be repeated for every new version of that Diff.

Your Github repository is a nice reference. I will do the same for T9797

To clarify: I certainly don't this dependency to be simply swapped for another dependency. Also having 2 server implementations isn't desirable either. I can't judge whether a PHP implementation can challenge the NodeJS implementation because I'm lacking the experience in PHP.

I think it would be nice to have out-of-the-box support for the clang linter.

I'd really like to see this happen. So far I haven't used Aphlict simply because I don't want to manage the extra dependency.
