Show HN: Chrome Extensions Archive

I'm archiving the chrome extensions, app and themes for multiple purposes:

- being able to go back to a previous version

- auditing version history (eg: somebody adding a malware)

- making my own extensions store with manual crowdsourced auditing before each update

- exposing the interesting data behind the chrome webstore marketplace

For now, only the archiving is here. What do you think ? Is it useful for you ?
