It doesn't take a complicated renderer to make a usable browser. The very first web dev built his own browser in a few megabytes of C and created his own markup language (based on SGML). Everything we use today is based on that work. So I think it's a relevant marker for when the line between advanced web development and "regular" coding gets blurry.

I don't think it's pointless at all. If advanced pure web dev is relatively less complicated ,even at the highest levels, then it's important to define where the line ends and begins. I might not have the answer, but I think it's an interesting question worth asking instead of leaving such definitions up to a God of the Gaps-like argument.
