Transtats covers 100 packages, while the change darknao and I do the following (stats are for f33):

* use dnf to download all srpm for a fedora relaese (21330 packages)
* detect po files (2230 packages have at least one po file, more file format exists, but it will be for the future ;))
* extract all po files (200 337 po files)
* deduct language list (344 languages)
* produce stats and consolidated files (16GB of files before compression)
* publish a website (2 GB once files are compressed)

The Transtats UI is good, but it really is focused on translation propagation accross system, bringing a huge complexity.
Sometimes we can't prevent complexity, but I don't really understand the main goal/use case transtats want to answer.
It may simply solve issues I don't have.

I'm really happy of the discussion we are having through this change process, I think we should use change process more often!
