One thing I like about the template of https://taler.net is the usage of javascript free translations of text (jinja2 is used), easy to select and write.
Actually that's the only reason why I favor it right now for my project web site launch over the haunt + guile mix Guix itself uses. I think translations of web sites are useful, necessary and important. It would be good if this can be provided in the long run by the Guix web site aswell.
