I'm quite happy that nowadays most tools have competently made themes out of the box, so that if someone wants to minimize risks from something like this and keep the extensions/addons they install to a minimum, that's pretty viable. Of course, it's also nice that it's possible to theme the software to such a degree and improve usability and accessibility in some cases, just that the feature requests about limiting permissions need to be addressed.
