Are people actually using Snap in containers? It feels like a convenience feature for desktop users.

They don't give you the choice. Applications are only avaliable as either a snap or an deb. With many you might want to containerise (ie Chromium for CI) being snaps. I dont belive they can work in unpriviledged docker containers.

There are Chromium debs for Ubuntu 20.04 available from the Linux Mint repo.

To get it Chromium under docker, I'm using the following params:

  --headless --no-sandbox --disable-gpu --window-size=1920,1080 --disable-dev-shm-usage

Which apps are you using via Docker, that are only available as a snap?

I understand that, it's just my impression with using Snap that it's used to ship desktop applications in a consistent way.

you cannot use snap inside a docker or any other OCI container, first of all snap is a containerised package as well so it doesnt make much sense but what is more important it requires SystemD and as far as i know if systemd isnt PID 1 snap deamon wont run and its CLI will output it cant run.
