It was shut off outside of whitelisted pages because a few bad apples were injecting Javascript with them, and I wonder if an update to MW would do anything to fix or restrict that.

I'm really kind of sad I've been sitting on a few MW namespace edits that are completely innocuous just because the page isn't whitelisted (I even brought up to staff via email (along with a whitelisting request) a change to make something clearer to editors on my wiki I wanted to make... probably close to two years ago... they didn't deem it worth it so they didn't do it or whitelist the page... which affected me taking a different locked message to them later (that is to say, I didn't do it)).

A less restricted MW space but still with precautions and/or punishment in regards to adding malicious code is something I'd much enjoy.
