Explanation for not using "trustworthy urls" is confusing

[mkruisselbrink]

In both the explainer and the spec you say "We don't entirely adopt the concept of trustworthy urls because it covers more schemes (e.g. data://123)", however data URLs are opaque origins, and opaque origins are not trustworthy.

There might be other reasons why using "trustworthy url"/trustworthy origin doesn't match what you want, but the given explanation seems wrong.
