My premise is that sysadmin/user time is more expensive than drive space. Seeing some real world examples of how Flatpak could save time over the long run would probably be beneficial for increasing usage.
Keep in mind I have no dog in this fight, I don't have a preference of one over the other. I only made that comment because everytime I see a Flatpak reference on the web it's always in the context of disk usage.
I did it a couple times when I really had to go. I usually waited as along as I could after class started so no one was randomly in the bathroom in between classes.
I was trying to extract some files from a a Linux image of one of those ARM boards. It was packed into the cpio format, and I had never used the format before. Of course I was trying to extract to a root owned directory and I sudo'ed it. I effed up the command and overwrote all my system directories (/bin, /usr, /lib, etc...). Thankfully I had backed up my system recently and was able to get it working again.
AI generated garbage.
