Yeah, you're right. Such change would require a lot of work, and the
befenits would be almost imperceptible, since the bottleneck of
performance in web applications is more related to DOM operations,
as you stated. So, looking more carefully to it, I also think that it
wouldn't worth doing this.

But, anyway, I was just sharing my thoughts with you developers.

Thanks for your considerations.
