Both refer to (mostly hypertext) documents.

All refer to (opaque) blobs.

Those are more and more obsolete.

That is a different language than CSS.

Because the attribute name refers to the type of the resource, not the
type of the name of the location of the resource.

What do you mean by inbound / outbound? In-band and out-of-band?

What benefit would that have? State a possible use case.
Be aware that this change would be not backwards compatible.
Keep in mind that more possibilities may needlessly confuse authors.

Whom would be helped by that?

Same question as above.

Solution C “Don't change anything” would require the least changes.

Does that matter?
Also: Your suggestion is founded on aesthetical reasoning. HTML is ugly.
