I agree with this.

(A)'' depicts my idea.

> BTW, Yutaka questioned what we should do with the ReadableStream when e.g. .text() fails due to invalid UTF-8 data. We came up with the following options:

I think 1 or 2 are reasonable and I don't have a strong preference between them. 1 would be text() doing nothing, and 2 would be text() calling `this.body.cancel(new TypeError("couldn't decode chunk!"))`. Maybe since we already think of text() as saying "I want all of the remaining data", 2 is best.
