This assumption needs to be validated. Would standard definitions be a silver bullet for learner navigation and employer value? To wit: We have standard definitions for degrees and yet the navigation and value problems persist in that domain. What if the more important issue is not what to call these programatic containers but rather how to describe the contents of what they contain?

As an experienced user, this claim strikes me as false.

I often start in a graphical file manager (nothing special, Nautilus on my system, or any conventional file explorer elsewhere), then use "Open in Terminal" from the context menu, precisely because of how much more efficient desktop file browsers are for navigating directory hierarchies in comparison.

NB: use of a graphical file browser doesn't automatically preclude keyboard-based navigation.
