[gatsby-theme-i18n] no seo support with URLs

[logemann]

Do i get it right that its not possible to modify the URL according to the current locale? This would be a SEO nightmare because with a contact.js page, you end up with:

https://example.com/de/contact/
and
https://example.com/en/contact/

Which is only ok for the second, because i dont want to have an english word in my german url, there i want "kontakt" and not "contact".
