I do have a tendency to check where the link leads before clicking on it, so the difference between those two is quite obvious to me: http://example.com/ vs http://xn--exmple-4nf.com/, but a lot of people probably do not do that.

I would definitely not click on the second one.

It would be nice if they could do the update with a single reboot. It is annoying to type LUKS password multiple times.
