DataView is dependent on ArrayBuffer which in turn has multiple other dependencies for typed arrays. Is it/should it really be possible to disable them separately? I think maybe a flag to disable all AB related features would be more appropriate.

I get the use for disabling stuff like ICU (Intl) and eval but is the idea that everything in the global scope except primitives should be able to be disabled?

I like the idea of being able to create environments for challenges like "Do X task without the Math object". But you might be right for the arraybuffer thing where we should make all those arraybuffer dependent features into one feature, what should we name it
