ad 2. you could introduce a ‘titlecase’ value that should use language-dependent rules, but may fallback to ‘capitalize’.
ad 3. The current text is only about case pairs like ‹I›/‹i› that may vary depending on language, it does not say anything about higher level rules, i.e. grammatical ones.

Btw.: I still think the new values ‘fullwidth’ and ‘large-kana’ need to be revised.

Lowercasing the rest is helpful for 


or, better yet, 

  acronym {text-transform: capitalize;}

but harmful for 

  <h1>Scrooge McDuck richest duck ever</h1> 

as long as we don’t have and use 

  <h1><name>Scrooge McDuck</name> richest duck ever</h1>
  name {text-transform: none;}
