True that it's not a US-only project, but consensus at WikiProject Television has shifted away from perfunctory inclusion of starts/ends in English-speaking nations, unless there is a noteworthy reason to do so.  If this were a German series, I would argue that US airdates aren't within the scope of our interest.  Similarly I think the German info is not necessary.  Yours is a reasonable argument for inclusion of the French dub, since it did make press. Anyhow, not worth a fight, but if it does get removed, the consensus is already there.
