So it's not Laravel that's making it hard, it just means that we'd have to rethink how we've tied our product to the infastructure. It's definitely possible, and if we go down that route, the software in Laravel will make it a breeze to export. We spoke with a chap on twitter who made a great point that we'd likely see more contributions since it's in PHP / Laravel. Less people know Go, and one of the big reasons we didn't feel the obligation to OS the new version was because next to nobody contributed to the Lite version.
And you're right. There are a segment of people who won't use analytics unless they're self-hosted. Totally understandable. We'll see what happens. It's not on the roadmap in the immediate future but we're not ruling it out.
