So I looked further into this and it looks like GitHub Sponsors can be set up to feed the funding directly into an existing Open Collective account.
However, GitHub sponsors requires all key decision-makers to explicitly support using GitHub sponsors. So if we do want to pursue this then I need all of @f-f, @singpolyma, @Nadrieril, and @philandstuff to explicitly affirm in this thread that they are okay with us accepting funding via GitHub sponsors (so I can link to this thread as evidence in the GitHub sponsors application). Vice versa, if you’re not okay with this, don’t be afraid to speak out and say so.
