Because of the size of the apt database (just one example, because apt is not the only package manager that needs to be taken into account) to begin with, I imagine anything outside of a distro's specific curation would make it really unwieldy. Having said that, it would be really nice if you could at least dump the apt, pip, cargo, vim scripts, etc to a common file and use it for setting up new systems with your personal standardized packages and package manager of choice. Even if you had to use the different apps to parse their own part of it, maintaining all the install info in one portable file would be glorious. Especially for folks with several systems, or systems that are rebuilt often, as seen in Raspberry Pi land, or any kind of lab environment. Setting up and maintaining a common Linux image, unless it is totally default stock, is really more of a pain than it should be.
