That would require that they themselves had a basis for a good faith claim, under penalty of perjury, that I was the original copyright owner. That opens them up to liability (as opposed to youtube, which just makes it easy for uploaders to file counterclaim notices). I sincerely doubt NPM would like to shoulder that burden. By uploading it, I have in fact given them a license, as far as I am able, but that doesn't matter if I never had the rights and they get sued for infringement.
