Yes but that cat is so far out of the bag that it's meaningless. The browser's model is "ship source code, and we compile and run it." I would love a universe where it would be possible to ship some binary artifact to browsers so that it can load it as if it was an already opened page, complete with local state and skip all the parsing/compiling steps.
Meh - every step down that road has been fraught with significant issues. See: Flash or Silverlight, for example. (Yes, I know, not quite the same as if the browser did it natively.)
One of the beautiful things about the web is the ability to jump into the dev tools and look at the code. I know it's harder than ever to actually learn from that now, and I predict you are correct that someday we'll get to the point where it's a binary blob delivered. But I'm not holding my breath waiting for it and certainly not advocating for it. I'll adapt when/if it happens, but I feel a bit of the "magic" of the web will die that day.
