Yes, true, but it is still needed. Monolingual text is still by far the
most common; to do more, structured markup is needed and I would not
propose adding that!.

Not at all. It is just information; the impleentation can do as much or
as little as it needs to. For example, far eastern implementations will
rely on the language code to differentiate Japanese, Chinese (simplified
and traditional) and Korean ideographs - these all have the same
character codes.
Notice that search engines like AltaVista now offer the choice of
searching restricted to a particular language. It is useful to indicate
the language.

It is orthogonal to the character encoding.

Yes but I think the intent with the dual keyword thing was that the
English keyword would be one from a list of registered keywords.

Phrases are OK; the "keyword" in PNG is already actually a phrase.
