There is no real advantage to the defer attribute since in HTML4 it is
only advisory, the UA is not required to actually defer the script
execution, and some implementations only defer it until seeing the
next SCRIPT element in the source. Relying on it the way your use case
does will work in very few browsers, and specifying this in HTML5
would increase backwards incompatibility for a very minimal gain.
