This sounds like the right approach to me: this kind of restriction is very easy to write in a lint tool, and our planned compiler plug-in approach is a perfect way to encourage people to write these plug-ins. But I'd rather be inclusive and give people the option to exclude, especially if it's not hard to express the exclusions.

I also agree that the risks are different for an AOT-compiled systems language, where the code lives in a single repository and is statically inspectable, than they are for web standards.
