But Samuel fixed that already, didn't he? Or is there anything left that
binman should do? We even now use mkimage to generate the magic BROM
SPL signature, and then let binman combine this with the FIT image into the
final binary. Or am I missing something here?

Or are you asking for patches that remove sunxi as the bad example from
the existing documentation? ;-)

Cheers,
Andre
