As a francophone, I have currently two options for importing templates to my wiki : either importing the english version then editing the labels to make them look french, or creating and copy-pasting every template manually, which is extremely fiddly.
As of now, I can work with it, but it would be a godsend to have the opportunity to directly import french template to my wiki, simply by adding the "fr" interwiki source to the import API.

Thanks in advance.
