This is becoming higher priority, since Composer is now showing this notice:
Warning from https://repo.packagist.org: You are using an outdated version of Composer.
Composer 2.0 is about to be released and the older 1.x releases will self-update directly
to it once it is released. To avoid surprises update now to the latest 1.x version which will
prompt you before self-updating to 2.x.
