Sure. And it's a tradeoff. The Tor and MPTCP projects came to mind, because I trust them. And there aren't many others that I trust.
My problem is that I prefer Debian stable, which is very conservative about package updates. But sometimes I end up using Ubuntu, because its repo includes newer packages.
Also, my core systems do not include anything except stable Debian. I only use third-party repos in project-specific VMs. I even use Oracle's MySQL Workbench in an Ubuntu VM. And even Windows 10 VMs, when I need Excel or other Windows-only apps. That is, compartmentalization.
