?Is there a central repository for SDIO vendor/device IDs similar to
?PCI or USB IDs?

No idea. I believe the existing repositories for PCI and USB are not
public either, there is just the information at http://pcidatabase.com/,
http://pci-ids.ucw.cz/ or http://www.linux-usb.org/usb.ids that
are maintained by volunteers and that are not authoritarive.

I found one list at https://github.com/systemd/systemd/blob/master/hwdb/sdio.ids
but it's probably very incomplete.

Maybe it should be maintained as a independent project...

?The vendor ID Espressif uses is 0x6666, which seems kind of bogus to me.

It probably is, but that's not important as long as nothing else uses
that ID.

Yes... I think the USB vendor ID of Allwinner, 0x1f3a, is also nothing authoritative.
