The spec uses a CDATA section in the example, for demonstration purposes
only. It's not a recommendation.
CDATA sections are of use for hand-authoring readability, but don't help
in machine-serialised documents. You don't get away from the need to
encode out-of-band sequences (notably ]]> is still invalid) so it
doesn't buy you any simplicity.

No, not really. Neither XML nor SVG mandate use of CDATA sections here;
a normal XML-encoded text node as produced by _serialize_xml is fine,
and works with all XML processing tools.
HTML serialisation has custom rules (the two CDATA elements) because the
HTML syntax is not XML. XML languages (including SVG and non-legacy
served-as-XML XHTML) have no such special cases.
(There are other problems in ElementTree's serialiser that make the
output unreflective of the infoset in certain cases, but not here.)
