Thanks for the follow up.  My understanding with ETags is you have to submit a request with the ETag to have the server decide if it needs to serve or not.  If not can you elaborate on how ETags keep static assets from being re-requested?

Forgive me but I'm at a loss for what you are trying to say here.  Are you saying first page load performance is not important?

Also here, what exactly do you mean by "load everything including the kitchen sink into the server process?"  Can you give some specifics? I'm again at a loss for your point.

Yes, sending headers from a .php file is easy.  How does the WordPress plugin developer do that for static files?  Are you advocating serving .js and .css files using .php, i.e. styles.js.php and styles.css.php? That is an option, but doesn't address first page load performance.
