Let’s paraphrase to “CLI applications are quite cumbersome to use under Flatpak as per the current implementation”.

Unless you set up your own aliases, you’ll have to write out commands like flatpak run ..., and if you don’t know the package name yet you’ll need to run flatpak list --app first as well

I hope that in the future, Flatpak gets some improvements for exporting CLI utilities into the user’s environment.
