support repo URLs without 2 path segments in update-package API call

Git repositories like https://git.tuxed.net/php-yubitwee are not supported with the update-package API calls because it only has on path segment.

$ curl -XPOST -H'content-type:application/json' 'https://packagist.org/api/update-package?username=fkooman&apiToken=<TOKEN>' -d'{"repository":{"url":"https://git.tuxed.net/php-yubitwee"}}'

{"status":"error","message":"Could not parse payload repository URL"}

Is there a way to support this without me modifying my Git server directory structure?
