Composer package reliance on storage.googleapis seems unreliable

Frequently get this error on composer install:

Unhandled promise rejection with Composer\Downloader\TransportException: curl error 95 while downloading https://storage.googleapis.com/civicrm/cv/cv-0.3.68.phar: HTTP/3 stream 0 reset by server in phar:///usr/local/bin/composer/src/Composer/Util/Http/CurlDownloader.php:398

Maybe the composer package could be handled by https://packagist.org/ ?

Reproduce the Composer install failure for cv-0.3.68.phar using the storage.googleapis.com URL, then inspect how this package is published and referenced. Compare Packagist as the proposed source; the work is done when Composer installs the package reliably through the supported distribution path.
