I think you're comparing apples and oranges.

Sure, having the ability to have a slower, fully instrumented launch is a good thing. But most of the time, there isn't a failure during launch, so why pay the penalty?

I think having a reasonable launch speed with the ability to report "common" errors is a Good Enough. And then having a slower launch speed that can report detailed errors for those who want/need more information.

Put it this way -- if you give the user the following choice, "You can have a fast launch at scale that has less-detailed errors vs. a slower launch with more detailed errors", in the common case (i.e., day-to-day runs), they'll choose the faster launch every time.
