Additional Info

In the course of upgrading typescript-eslint from 3.9.1 --> 5.49.0 I started getting a ton of "no-used-var" failures from some of our older projects that still use the old "export = X", "import X = require(...)" syntaxes.

I'm guessing this happened with the scope analysis changes from 4.0? Regardless, I know it's a bit silly considering how out of date "export =" is, but I wasn't sure if they're supposed to be supported or not.
