--- Comment #43 from Anne <annevk@annevk.nl> ---
Audio, video, crypto, fetching (XMLHttpRequest, fetch()), all potentially have
the separate process semantics. The only case I can think of that might not
require copying is text encoding. ImageData specifically does not do copying
but requires upfront work (only takes Uint8ClampedArray).

At the moment everything that says sequence<> is a copy too and not always
strictly required I suppose.

It seems like IDL should provide the tools to do both and we should just be
careful when designing/reviewing APIs as to what is actually required.
