I am in the same camp in general, too, but in this particular case
the "user experience" is already stretched to a degree that people
start pointing fingers ;-}

I guess it's hard to come up with a benchmark that everybody
would consider authoritive. I could run a few tests for scenarios
I am interested in, though. Am I right in assuming that I could just
pull one of the archer archer-keiths-* branches? Would that be
archer-keiths-linkage_name-redux?
