Yes we advertised it as a feature to all new signups, with a link to request limits. It's not equivalent to a button, the dirty secret is that when people requested it, I planned to put a notification in my calendar to go look at their usage the last day of the month and adjust their bill accordingly. :)

We were concerned about spending time on marginal features that didn't actually matter much to people, so we "launched" it without building it to see if anyone cared.
