From what I can tell, packagist doesn't allow changing that.
Alternative method, create a new user account and do the routine over again?
This is the bummer solution: https://github.com/composer/packagist/issues/47
So this does work
Does or doesnt? Sorry
I setup https://packagist.org/packages/cmb2/cmb2, which should be the new final source.
Since we can't keep download stats, I'll keep a screenshot of them here for posterity.
