I think the explanation is a lot simpler - iOS to date does not correctly support most European languages. Using Siri in anything other than English is a pain and using the Translate feature is available in only a handful of countries.
For anything remotely powerful enough, iOS will have to send voice to some server for processing and that’s a privacy shit show.
That seems ridiculous, this is a translation feature. Do you think it is aimed at translating American to Canadian? Those pesky niche European languages are hardly spoken in the Americas so maybe that is the case.

British to American.
Genuinely useful to me.
I'd prefer American to British, though.
What languages is it mean to translate then? Different accents of English?
Mostly Spanish and Chinese. Arabic and Hindi will already be difficult.
German is on the list of supported languages. That can't be the reason why it's not available in Germany. Although as an Austria I must admit their German is a bit weird.
