That would help with automation. More frequent updates. Then git tag signing, deterministic builds and release quality assurance would be sorted out.

Motivation:

All packages not coming from Debian like Tor Browser (not packaged at all) and Tor (newer versions from deb.torproject.org) is a major non-fun hassle maintenance burden.

• watch upstream package updates
• upload to developers repository
• test
• upload to testers repository
• have testers test it
• upload to proposed-stable repository
• have testers test it
• upload to stable repository

Since all of this needs mental resources, time, remembering things, and cannot be done in connected working hours (since time has to pass), it's a major hassle.

Most of the time, no issues are caught. But if there was an issue, it could be huge, such as:

• Tor no longer connecting, requesting all users to apply manual steps to solve it
• apt-get package management is broken dependency state
