are there metrics on how es6 and future proposals affect javascript load-time for webpages?

[kdex]

I don't think that this is a well-defined question. Is "load time" equivalent 
to "parse time"? Is it "compile time"? Is it both? Is it something else? Are 
we talking about engines that don't generate native code and thus maybe 
"interpretation time"? What are we measuring when you say "JavaScript load 
time"?

First of all, ECMAScript requires an environment, which may or may not be a 
browser. So it might not necessarily make sense to assume "web pages" or 
browsers in the first place.

Aside from that, a great deal of "load time" (?) will likely consist of the 
time needed to parse the source code. Anything else is mostly implementation-
specific and thus varies from engine to engine.

Could you state your question more precisely, please?
