I'm sure a lot of people would love to embed SQLite without using cgo. This also removes a big barrier to porting older libraries which is likely to be the first use case.
Yeah, I'd love to be able to do that too. Bolt and LevelDB are nice but sometimes you just want SQL and having SQLite on board can be incredibly helpful. But if you have to use cgo for it complexity goes up a notch, even for something theoretically simple like distribution of the binary.
