Agreed.

What value does the init-worktree-config subcommand provide; why
shouldn't we just get rid of it?

I know Eric was strongly suggesting it, but he was thinking in terms
of always doing that full switchover step, or never doing it.  Both
extremes had the potential to cause user-visible bugs, and thus he
suggested providing a command to allow users to pick their poison.  I
provided a suggestion avoiding both extremes that doesn't have that
pick-your-poison approach, so I don't see why forcing users into this
extra step makes any sense.

But perhaps I missed something.  Is there a usecase for users to
explicitly use this?
