It makes it a little bit easier to do, but it is not difficult to replicate this effect without changing the URL in the title - using a redirected URL and changing the redirect address, for example.
I think that this small increase in the way this kind of attack can be delivered is more than counter-balanced by the convenience of having editable titles.
Most subreddits also blocked redirect links for (partially) reason.
