Because the HTML serialization should be parseable by legacy
user-agents.  <script src="foo" /> will be treated the same as <script
src="foo"> by all existing UAs in text/html, and all subsequent
content on the page will become part of the <script> tag, possibly
causing the whole page to vanish (maybe less than the whole page if
there's a </script> somewhere).  The spec doesn't permit behavior in
text/html that's incompatible with existing UAs without good reason.

You can, of course, use the XHTML serialization, in which any empty
element can be self-closing.
