What problem does it solve? Just use the package manager provided by the platform...right? Especially given the problem of package naming, it’s different even between Debian and Ubuntu :/
I haven't encountered this for all the standard applications I end up installing on my machines (things like htop, nginx, etc).

It solves the problem of me having to think about what OS I am on before I can install something (and if it's something I don't use a lot I might need to google the package manager syntax).
