I'd _like_ to see arbitrarily large amounts of detail on the modeline
provided that we can display this information safely and efficiently.
Why not? If one VCS in particular can't provide this information in a
timely manner, sure, we can override vc-mode-line-string and display
something more spartan. But the ideal should be to show as much as possible.

Yes, I think that thread got off on the wrong foot. It's better now.
