The 30-script limit exists because, currently, we copy every script to every server on our edge upfront, hence the storage is rather expensive and we don't want people storing a bunch of scripts they aren't actually using. We'll likely improve this in the future by allowing you to have more scripts as long as you're OK with some of them being fetched from a central location on-demand (which might make them a little slower to start up). I don't have a timeline for when we'll implement this, but it is a common request.
