I can appreciate the desire for a timely release of the next major update. Yet, I am glad to learn of these added security measures.

After your community grows, it will become a prize for hackers who can infect many others from a single place.

If your site becomes infected, you become the instrument of malware being distributed to others - which is sickening. Your hosting company can then deny you service. Your site may also have "unsafe warnings". And of course, you can lose your search engine ranking. Pretty heavy stuff.
