Transifex already does this:

the front page has translation completion percentage for all modules
combined. Front pages for each individual module give percentages for
that module. Of course, this is for Fedora modules - things like
anaconda, the release notes, etc - but that's all we can realistically
track anyway.
Translation coverage information can be extracted at build time. In
fact, Richard recently wrote some code to do just that for appdata.
