Allow me to restate:

"Look how long Servo, one of the few examples of a mostly-from scratch browser engine that we can look to and thus compare (although technically some components of Servo are borrowed from Gecko so even it is not fully a from-scratch effort), is taking to write."

The point was to find any comparable effort to demonstrate what an undertaking this is. Servo was started 7 years ago by one of the few companies with engine expertise. Although, granted, I agree that perhaps framing it as a rewrite might lead you to believe more effort is being placed there than actually is (although I don't think it's totally unfair to look at it that way given their original embedding goals).
