I've updated the language used (and added chat.js). However, please don't take it as an insult - the page is about a specific kind of JS page: those that are actively run by the software in different contexts.

The reason other pages are still locked is because we need to make sure they are not imported into the community JS pages - something that is being enforced via the JS review process. Once that has been sorted out, we should be able to re-enable editing there.

We agree, the error message should be updated - I'll make sure this is on the team's list.
