Seo Friendly URLs for different languages

The way opencart treats different languages is a huge drawback in my opinion. Using the same URL for a product in all languages is very bad for indexing according to google guidelines.

Keep the content for each language on separate URLs. Don’t use cookies to show translated versions of the page.

I know there are some community-developed extensions out there that provide this feature. However they often collide with other extensions that use the standard OpenCart link system. Multilanguage urls is a must feature for a software that focuses in selling products over the internet.
