I have been pondering if it's possible to tell vcsh about directories it's
managing exclusively.

Though even that starts to break down once you have

  zshrc
  zshrc.local

which carry public and private configuration.

Yes. I keep wondering if git smudge/clean filters could be abused to do
this.

Both the problems of "global ignore file" and "caching of ignore data" are
still open.

Still, you need to ensure that the common case, i.e.

  vcsh enter foo
  git add bar

heeds the ignore data, no matter where it sits.

The actual adding is prevented by gitignore; but only to some extent as you
more or less start to default to `git add -f`.

I did think about a `vcsh status` a lot recently and a file tracked by two
repos would be an obvious candidate of things to list.

The more I think about it, the more I am convinced that there's a way to
safely and sanely implement `vcsh add` and `vcsh commit`.

I cannot think of a smart way to reuse these data. The way I think

Renames that span several machines are still an open question.
