I'm not sure how you suggest the semantics be simplified. I'm 
in favor of simplicity but...

See section 6.4 paragraph 2. Is there more needed?

I agree that it might be confusing, but I personally see a great
difference between me and my web page, and that when I say
"http://larry.masinter.net", I have to mean one or the other
(or perhaps both), but that they aren't the same. I haven't come
across anyone who was confused about what 'tdb' was trying to do.

I haven't seen anyone asking this question... are you?

Those are good questions, but the answers depend on context,
and I can't find a context where there is an actual question
about it....

There are consequences.
I don't think that providing a way of distinguishing me from my web
page "introduces" the consequences.

Because people want a URI, something that fits into the URI syntax
in which the "scheme" determines what you mean.
