"hello ${'world'}" should be linted.

At the moment, the prefer_single_quotes rule seems to intentionally allow that syntax. The reasoning is laid out here.

Thanks, it can make sense for some code. And I guess that's why expressions in string interpolation are not linted:

    "${""}"; // OK
    '${''}'; // OK
    '${'${'${'${''}'}'}'}'; // OK
    '${"${'${"${''}"}'}"}'; // OK
