There are annoying edge cases where formatting does matter, such as whitespace around HTML text nodes, e.g.:

  <span>foo</span>

vs:

  <span>
    foo
  </span>

Sure, but the same goes for verbatim strings, or leading whitespaces in python. "Code formatting" questions usually only concern themself with those degrees of freedom that do not alter the semantic meaning of the code.

		Agreed, but my experience is that many formatters will try to "help" by formatting non-code, thereby breaking something.
