While I think you are right in some cases like cashier, isn't
this
discussion really about the Fedora Workstation?! Since for this the
target user is a developer, can we just agree that in this case the user
needs both CLI and GUI apps (although some developers certainly sticks
to one of them).
The gist is that
* Nobody _should_ need to use a terminal: non-developers¹ don’t need it, and developers
deserve a better environment. It’s “only” a matter of writing lots of new software.
AFAICT Workstation would in some ideal future want to get to this state. (And non-Linux
operating systems are getting closer and closer to this ideal over time.)
* _Currently_ most Linux developers do need to use a terminal.
So there is no right answer, only a trade-off: Make terminal usage discouraged and
difficult for current users, and hopefully get better non-terminal environment in the
future, or make terminal usage easy and the generally recommended way, and give up hope on
the developer UI significantly improving for the future users.
