I'm going to use a big notice here: None of this is inherently safe to use as a client. This is similar security profile as a database driver. This API has no row level auth or anything like that. Unless this is explicitly what your product is doing, like within PlanetScale, this is what powers our Console, don't use this in a browser.
With that said, I personally have no real opinions on this topic. It's pretty far out of my wheelhouse. I think that's more something like Firebase and gang, but that's not something we're gunning for at the moment and aren't trying to replace that.
