That statement is falsified by the advent of programmable completions. Nothing stops us from integrating context sensitive help into the shell completion mechanism. The shell could display a help text next to each item of a completion list, or you could press keyboard shortcut to get help to the command your cursor is positioned on. shellcheck could highlight a bash command while you are typing it. All that would not change the fact that a shell is a CLI.

Completions are very limited in their surface. And you still need to learn where to start to get the completion.
