  # The newest Git feature that Braid is currently known to rely on is
  # `receive.denyCurrentBranch = updateInstead` (in
  # spec/integration/push_spec.rb), which was added in Git 2.3.0 (in 2015).  It
  # doesn't seem worth even a small amount of work to remove that dependency and
  # support even older versions of Git.  So set that as the declared requirement
  # for now.  In general, a reasonable approach might be to try to support the
  # oldest version of Git in current "long-term support" versions of popular OS
  # distributions.
