Usually context makes the nominal use of "use" clear : "many uses", "the use",

"some uses". I'm  not persuaded that "use case" disambiguates any more reliably.

How do supermarkets display their wares?

For some use cases they use cases.

Metacomment. While the "use" in "nominal use" above must be a noun, "nominal" isn't compelled to have the intended meaning of "being a noun". It's a game of whac-a-mot. Kill one ambiguity and spawn another.
