You can avoid that one by customizing `vc-follow-symlinks'.
Maybe you can make an argument in that bug report for changing the
default for the above variable...

If "emacs --daemon" asks a question when starting, one should be able
to answer it from the terminal, the same way it is done when emacs is
started in batch mode.
In general such a question is due to what the user has in .emacs, we
can't really prevent the user from shooting himself in the foot.

This assumes that there's a default correct answer to any of these
