You could implement this for yourself as a shell function sort of, by wrapping git, but it's a bit crazy, something like:

function git() {
  # check if first argument is checkout, otherwise exec git
  # check second argument, and parse git-worktree to determine if it
is checked out
  # if so, just cd into the directory
  # else exec git normally.
}

I'll leave actual implementations to the user. Note at least for BASH, you need to actually do this as a function alias.
