The worktree feature has been used by several people
already (me included), and do far the only issue which
requires change in repository layout is the config
separation. Isn't it enough to be confident?

As I noted in another email, I would not expect to be N>2
soon. At least not more likely than incompatible change
because of some other reason. And the support for an older
version can be as little as one-time upgrade to the current
N (preferably with confirmation from user).

Users definitely would not benefit if there is release
feature with note "anything you do can be lost after you
install next version of git"
