Good to know! I've generally understood that the bar for package inclusion for both Debian and Ubuntu is fairly high (where Debian wants you to push to them and Ubuntu will pull from you).
Our setup today is simply to add an apt repo[1] (of which there is just one domain for all Microsoft Linux packages), and then you can `apt install`.
We also ship pretty minimal Ubuntu and Debian (and Alpine and a bunch of other) container images here.[2]
Oh, and we ship on the Snap Store if you're using Snapcraft stuff.
