It's done really late, because it's plausible that the user-level or repo-level hgrc would contain ui.tweakdefaults=True. It checks for all the config entries it wants to set, and if anything is already set to a value it doesn't make any changes.

You would not get relative status.

You would also not get relative status.

Yeah, it's definitely rough around the edges, but I think it's better than not having the feature.
