I agree that many people get confused at this point. However not many
people are prepared to uninstall due to the associated issues with
removing deps. Especially a dep as important as jack.
It's also misleading to refer to the existing proven toolset which is
quite useful to many professionals as "possibly dead end". That's
verging on fud.
