You do you, but I think it's rarely worth it having the absolutely newest version of something. The Debian version of a package may be older, but often has the advantage of being well-tested. And the Debian version of ncdu is all I've ever used and it has worked well.
uniget, huh? That's not a package manager I've ever heard of before.
In other words, we’ll no longer need to rely on commands dpkg -l | grep some_package_name to find out if a package is already installed
That's a strange way to go about that, and strange to suggest using logs to figure out if a package is installed. I recommend using apt-cache policy some_package_name.
