XHTML FAQ: "XHTML 1.1 documents as text/html?"

Dear HTML Working Group,

  On http://www.w3.org/MarkUp/2004/xhtml-faq.html#mime11 you write:

[...]
  Why is it disallowed to send XHTML 1.1 documents as text/html?

  XHTML 1.1 is pure XML, and only intended to be XML. It cannot reliably
  be sent to legacy browsers. Therefore XHTML 1.1 documents must be sent
  with an XML-related media type, such as application/xhtml+xml.
[...]

This is inconsistent with RFC 2854, the XHTML 1.0 Second Edition
Recommendation and the XHTML Media Types Note which both do not disallow
serving XHTML 1.1 as text/html. And I think that your experience with
delivering the XHTML 1.1 Recommendation for now more than three years as
XHTML 1.1 as text/html without any remarkable problem, clearly suggests
that the unreliability you discuss either does not exist or is not
relevant. Please change the text at least to reflect the specifications
I cited.

regards.
