Comment (by karsten):

 I started working on a CollecTor module for retrieving and storing
 fallback mirror lists. It uses [https://www.eclipse.org/jgit/ JGit]
 internally. In the first run it clones `tor.git` and copies all versions
 of `fallback_dirs.inc` to the local file system. In subsequent runs it
 fetches `tor.git`, checks for updates to `fallback_dirs.inc`, copies only
 new versions to the local file system, and pulls from origin/master. This
 code is not ready for production yet. I'll resume working on it as time
 permits. If there are questions/comments on the general approach, I'm
 happy to hear those!
