Hi Jerome,

Hello all,
I think it would be nice to have the possibility to post-load some of
the JavaScript extensions, as a way to ease performance best practices
for developers. (See
http://developer.yahoo.com/performance/rules.html#postload for example).
It would also allow people to easily add hungry third party scripts
(like the google analytics tracker) in a non intrusive manner and not
sacrificing performance (no need to modify/override htmlfooter.vm for
example, a simple SX always-use will do).
I see different ways of doing that :
1) Either we say all document JSX are post-loaded, and
we move the hook
down the DOM just before the closing </body> tag.
This poses a problem in WYSIWYG editing mode. I'm currently loading the
JSX in edit mode in order for the page to look as in view mode. Placing
the hook inside the editable body is dangerous.

2) Either we have 2 hooks and we leave it as an option
to be post-loaded.
My preference goes to 1), as I don't see any good use case where a
extension would need not to be post-loaded; and 2) is not so elegant to
implement with the current SX mecanism.
WDYT ?
(Note: I'm not talking about file-system extensions here (JSFX), though
the question could be asked for them as well - I need to give it more
thoughts)
Jerome.
