Currently yes, but I've gotten a lot of the same feedback and I'll make it optional in the next release (within the week :)

Follow us on Twitter (http://twitter.com/safe_app) or GitHub (http://github.com/safeapp/safe) to be notified when it happens.

(If you can't wait, you can always edit the source and produce your own build. Those system changes aren't necessary for Safe to function.)
