Never heard of it before but hey, it would be great to have it in there.
Note that all the packages are provided by the distributions, not us - that is how it works on Linux in general... When they are included officially (like in openSUSE, Arch) that makes it super easy to install for users.
WRT packages vs tarball with our updater, I think the updater is generally a better solution because I know and trust the team maintaining that part (us...) but of course it is totally understandable that some people prefer packages or trust their distribution to keep things up to date.
Good that there is choice!
