I'm a big fan of encrypted connections. Towards that end, I just did a survey of all the apps in @fdroidorg to see if any of the source repos would not work with https://. This includes the over 5000 apps and all of their git submodules. All the git URLs that did not have encrypted connections (e.g. git:// http://) could be upgraded to https://. So I filed a bunch of merge requests, and am working towards forcing https://
