Even if I agree, I see at least potential issue for existing JSX, since code executed during page loading may be broken by a post-loaded extension. I think that we (at Softec) have at least one extension that would break, it is a implementation of the astable for backward compatibility. Another potential issue is our field validation extension that may be called by user interaction before the end of the page loading (browser dependent). So to avoid that, 2) is not a bad option either.
