Sigh, does anyone know how to configure git-series (or git commit) to add
it automatically? I know how to do that for git format-patch, but it
seems git-series doesn't use it.

Yes, exactly.

Technically it is possible to package stubdomain as just kernel binary
(with initramfs embedded), so this option wouldn't be needed at all.
But it's far less convenient for debugging and customization.
