Yet in practice, only the big boys are allowed to become "Trusted Publishers":
> In the interest of making the best use of PyPI's finite resources, we only plan to support platforms that have a reasonable level of usage among PyPI users for publishing.

How long until everyone is forced to launder their artifacts using Microsoft (TM) GitHub (R) to be "trusted"?

I wrote a good chunk of those docs, and I can assure you that the goal is always to add more identity providers, and not to enforce support for any particular provider. GitHub was only the first because it’s popular; there’s no grand evil theory beyond that.
