This was discussed since the beginning of this feature. I recall that
the index reflects worktree, and because we mark CE_NO_CHECKOUT on
file basis, it's best to save the information there, not separately.
We do save high level information to form the checkout area (sparse
patterns) in the last half, but basically you should be able to live
without that.

So if a user changes worktree without updating index, they will have
the same results as they do now: files are shown as modified if they
don't have CE_NO_CHECKOUT set. If those files do, they are considered
'orphaned' or staled and are recommended to be removed/updated to
avoid unexpected consequences (not availble this this first half
series because that belongs to "git status").
