Branching from just a part of a repository?

But that would hide the history of non-hidden files.
Committing the files into a fresh new branch already gives you that.

If you really only want to hide some "tail" of the history, you can
already do that: make a stacked branch and keep the tail of the
branch secret (so any attempt to fetch some earlier part of history
would simply get something like a network error).
