Review comment:
Translations will not be available until they were read from the
bootstrap data via
[`preamble.ts`](https://github.com/airbnb/incubator-superset/blob/9a59bdda486f90b8faeafdc79af3bcdbb7c3d250/superset-frontend%2Fsrc%2Fpreamble.ts#L32)
(prepended to every JS entry point script).
I think the usage here is fine, but I would recommend rename `undefined` to
`undefined_vars` (including on the Python side), as `undefined` is a reserved
word in JavaScript. This may cause confusion.
Another solution is to instead of using translation strings, you could
present them as a two column table with "Variable Used" and "Suggestion(s)".
