Sure. It also sounds like you liked the pithy answer opportunity more than you than you care about the substance of what I was saying. Which is a shame, the dialogue on Hacker News is generally better than that.

Or to put it more explicitly: the scenario you lay out is rare enough to be of no consequence compared to the much more frequent instances of unremarkable legacies getting a massive handicap.
