Maintainers could `sudo touch` their own files, which is what I did before.

If extensions have symlinks to other packages, touching on postinst is not going to help either, you will need to do something much more complex.

Is this really going to be a common scenario? To deal with it, we will need to set up a dpkg trigger to walk the tree every time it is updated, and touch manifest.json to the latest timestamp out of all the files in the tree. (On the plus side, this solution also avoids postinst scripts in the webext package(s) themselves.)

I already implemented touching manifest.json during the build yesterday, so the repo is already updated.
