As a web developer, why would I even care about that? I care more about whether it adheres to web standards; or in the absence of a standard, whether it is in-line with other leading browsers.

If all of our leading browsers use the same engine, the answer to that is one and the same.

I mean, I get the point you're trying to make, but the argument doesn't really fit with what I'm saying. As far as I'm concerned go ahead and rewrite Blink in Rust or Go or Common Lisp. As long as it is the main engine, or adheres to the web standards, it really makes no difference to me.
