O que costuma-se supor

An inner pandas DataFrame.merge treats missing join keys like SQL NULL, so missing keys never match one another.

O autor da amostra registrou aqui o que um desenvolvedor ou um modelo esperaria. O contrato abaixo é o que de fato rodou.

Contrato

• With two missing Int64 keys on each side, an inner DataFrame.merge returns four missing-key rows containing every left/right pair.
• validate='one_to_one' raises pandas.errors.MergeError when the only duplicate keys on both sides are missing values.
• After each side is reduced to one missing key, validate='one_to_one' succeeds and returns one missing-key match.
