We _can_ roll out builds faster - but as we're using multiple tiers of framework, we have to make sure that the back end is still compatible with the front end. The back end is only promoted once per day, and if there's been a breaking change since the last promotion then we can't move the front-end up until the back end is also promoted.

And as multiple front-ends use the same back-end, we can't just move the back-end up whenever we feel like it, or we break everyone else's UIs.
