It may not be limited to address (other fixed length datatype is also potential). We do not know if we manually padding the data, can EVM still recognize.

The decoder needs a rule for handling such type of error. We need some research and test about this topic.

~If I understand correctly we currently throw an error in this case. However we want to do research to be able to decode in such case?~

NVM, I see the discussion here.
