We have --destination and --gzip-level instead of --pack-destination and --pack-gzip-level. We should consider changing these for 1.2, or supporting both.

Yea we should support as an alias, for example:

    const child = spawn(
      packageManager,
      packageManager === 'bun'
        ? ['pack', '--destination', tmpPath]
        : ['pack', '--pack-destination', tmpPath],
      {
        cwd,
        stdio: 'inherit',
      }
    );
