Yes, those work fine: https://playground.oxc.rs/?options=%7B%22run%22%3A%7B%22lint...

For that matter, TypeScript's version of decorators ("experimental decorators") also works: https://playground.oxc.rs/?options=%7B%22run%22%3A%7B%22lint...

What's not supported is the current draft proposal for standardized ECMAScript decorators; if you uncheck experimentalDecorators, the decorator syntax is simply passed through as-is, even when lowering to ES2015.
