Perhaps. Could you describe some convincing scenarios? I'd hate to add
a new interdependent property without good reasons.

Another option would be to preserve white space in the content and let
'white-space' property decide how to treat it. E.g.;

  @page { @top-center { content: string(header); white-space: pre }}
  h1 { string-set: header content() }

Yes, it's also simpler.

I like ID's better than introducing named elements. As you see in the
section on Generated Lists, ID values are use on the right side.
However, the current issue (getting uniform sizes for leaders on the
same page) may not in itself require such (relatively) complex
solutions.

Agreed, it feels right.

Yes, I'd rather have it as a value.

Agreed.
