Neither of those were the case; this was what I was trying (in too many
words) to say.

The build-aux/bootstrap script contains these lines related to
bootstrap-sync:

  # Set this to true in bootstrap.conf to enable --bootstrap-sync by
  # default.
  bootstrap_sync=false

then later:

    --bootstrap-sync)
      bootstrap_sync=true;;
    --no-bootstrap-sync)
      bootstrap_sync=false;;

then later:

  if ! test -f "$medir"/bootstrap-funclib.sh; then
    # We have only completed the first phase of an upgrade from a bootstrap
    # version < 2022-07-24. Need to do the second phase now.
    bootstrap_sync=true
  fi

  if $bootstrap_sync; then
    prepare_GNULIB_SRCDIR
    upgrade_bootstrap
    # Since we have now upgraded if needed, no need to try it a second time 
below.
    bootstrap_sync=false
  fi

As you can see, it doesn't matter in any way what I set in my
bootstrap.conf file or the command line: the if-statement says if
bootstrap-funclib.sh doesn't exist, then bootstrap_sync will be set to
true regardless of its previous value.

Since obviously I don't have that file (since I was using the old
bootstrap), bootstrap_sync is set to true and the bootstrap sync
happens regardless.

As best as I can tell, this is a bug.  If it's not then I don't
understand the point of having the option at all.
