Yes, I'm breaking the current (incorrectly implemented) ABI to fix it
and make it consistend with other use (for example, "fatwrite").  As
is, it can only be used from the command line, but not from any
scripts that refer for example to ${filesize}.

I do not see any such need.  Hex input base is the established and
documented default - ext4write is not a special command, so why should
we mention this here when we do not mention it anywhere else?

Best regards,
