Comment:

 The proposal has been merged to the master branch of torspec as
 proposals/210-faster-headless-consensus-bootstrap.txt

 I have a working implementation for IPv4 that requires:
 * the feature15775-fallback-v8 branch from #15775 at
 https://github.com/teor2345/tor.git
 * a list of fallback directories to be placed at src/or/fallback_dirs.inc
 (a sample list is available attached to #15775)
 * the feature4483-v7 branch from #4483 at
 https://github.com/teor2345/tor.git

 The implementation is missing:
 * some unit tests,
 * fine-tuning of the connection schedules,
 * thorough testing.
