### What needs to get done Remove support for the dispatcher's default command. ### Why it needs to get done A default command was added to craft-cli to maintain compatibility with Snapcraft. Default commands aren't a good UX practice and no other craft app supports them. Snapcraft 9 dropped support for the default command, but craft-cli still needs to provide a helpful error message: ``` Running snapcraft without a command isn't supported. Use 'snapcraft pack' instead. ``` Craft-cli can fully drop support when Snapcraft 10 (core28) is released, as this version of Snapcraft will do what the other apps do (show the help text).
